ICC tweaks PowerPlay rules for shortened T20Is

The International Cricket Council (ICC) has announced significant updates to the Playing Conditions for Men’s Twenty20 Internationals, set to take effect on July 10, 2025. These changes primarily focus on how PowerPlays are calculated and the regulations surrounding concussion replacements, with an additional clarification on the use of saliva on the ball.
PowerPlay Rule Changes
The most notable alteration affects PowerPlay calculations. Previously, PowerPlay overs were rounded to the nearest over. Now, the length of the PowerPlay will be rounded to the nearest ball. This ensures the PowerPlay more closely maintains its approximate 30% proportion of the innings, especially when matches are shortened.
For example, under the old rules, an 8-over innings had two PowerPlay overs, and a 9-over innings had three. With the new rules, an 8-over innings will have a PowerPlay ending after 2.2 overs, and a 9-over innings will see the PowerPlay conclude after 2.4 overs.
This method, which has been successfully used in England’s T20 Blast, allows for fielders to adjust positions mid-over, as explained by the ICC: “In the 8 over example above, the umpire will make the signal after 2 balls of the 3rd over, at which point three further fielders are able to drop back from within the circle.”
Concussion Replacement Updates
The ICC has also revised the rules for concussion replacements to ensure a more level playing field. Teams are now required to nominate and name specific concussion replacements to the match referee before the match begins. This aims to eliminate any potential home team advantage that might arise from having a larger pool of players available.
Teams are asked to nominate one player for each of the following categories:
- One wicketkeeper
- One batter
- One seam bowler
- One spin bowler
- One all-rounder
The ICC acknowledges that Associate Member teams may face challenges in nominating five distinct players, especially when playing overseas. To address this, flexibility is provided:
- A batter can be nominated as a replacement wicketkeeper, though the referee may require them to keep wickets if used in that role. Alternatively, the referee may allow another player in the starting XI to keep wicket at their discretion.
- Teams can nominate the same player for multiple categories. For instance, an all-rounder could be nominated for both a batting and bowling slot. However, the over-riding principle of a like-for-like replacement remains, meaning an all-rounder replacing a batter would likely be restricted from bowling.
- Concussion replacements are not restricted to the playing squad; teams can nominate any eligible and qualified player.
The match referee retains the discretion to ensure replacements are as like-for-like as possible, even considering players outside the nominated list in exceptional circumstances.
- For Home Teams: It’s easier to nominate five specific players, as they can select from any eligible player in the country, even those not in the match squad.
- For Away Teams: With typically smaller touring squads, away teams should nominate the three non-playing XI members on the form, with two of them nominated twice. If a replacement is needed, it will be handled based on the like-for-like principle.
Saliva on the Ball
A new clause has been introduced regarding the use of saliva on the ball. If any substance, including saliva, is used to illegally alter the condition of the ball, it will now be mandatory for the ball to be replaced. This prevents teams from deliberately applying saliva to force a ball change under specific circumstances.
Please note: These updated playing conditions apply solely to Men’s Twenty20 Internationals for now. The Women’s playing conditions are slated for an update in October.

Deeper Dive into the ICC’s New Playing Conditions for Men’s T20 Internationals
The International Cricket Council (ICC) has unveiled pivotal amendments to the Playing Conditions for Men’s Twenty20 Internationals, slated to take effect on July 10, 2025. These revisions, meticulously crafted to enhance fairness, strategic depth, and the overall integrity of the game,
primarily revolve around refined PowerPlay calculations, a more structured approach to concussion replacements, and a crucial clarification regarding the use of saliva on the ball. Each change carries specific implications for players, officials, and the broader cricketing ecosystem.
The Nuance of PowerPlay Re-calibration: A Shift to Ball-by-Ball Precision
The most impactful change, from a tactical standpoint, is the overhaul of PowerPlay calculations. Historically, PowerPlays in shortened T20 matches were rounded to the nearest over. While seemingly straightforward, this method could lead to significant discrepancies in the proportion of fielding restrictions relative to the total innings length, especially in heavily curtailed games. The ICC recognized this imbalance and has now mandated that the length of the PowerPlay will be rounded to the nearest ball.
Why the change?
The fundamental principle of a PowerPlay is to offer the batting side an initial advantage with limited fielders outside the 30-yard circle, broadly constituting 30% of the permitted overs. When an innings is shortened, rounding to the nearest over could drastically alter this percentage. For instance, consider an eight-over innings under the old rules: with two PowerPlay overs, the restricted period constituted 25% of the total overs. A nine-over innings, with three PowerPlay overs, would see this jump to 33.3%. This swing could disproportionately impact a team’s strategy and scoring potential.
The new “nearest ball” approach ensures that the PowerPlay remains much closer to its intended 30% proportion, regardless of how many overs are in an innings. Let’s revisit the examples:
- Eight-over innings: Instead of two full overs, the PowerPlay will now end after 2.2 overs (two overs and two balls). This means the fielding restrictions persist for exactly 30% of the total 48 balls (8 overs x 6 balls).
- Nine-over innings: The PowerPlay will now conclude after 2.4 overs (two overs and four balls). This translates to 30% of the total 54 balls.
This granular approach maintains a consistent balance between bat and ball in truncated games. The ICC’s rationale stems from the successful implementation of this system in England’s domestic T20 Blast competition for many years. Their experience has demonstrated that ending a PowerPlay mid-over presents “no difficulty for players or officials.”
Practical Implications for Players and Umpires:
For players, this requires a heightened awareness of the exact ball count within an over. Batters will need to quickly adapt their approach as the PowerPlay transitions mid-over, and fielders will need to be ready to adjust their positions promptly upon the umpire’s signal. The ICC has clarified this operational aspect: “In the 8 over example above, the umpire will make the signal after 2 balls of the 3rd over, at which point three further fielders are able to drop back from within the circle.” This ensures a seamless transition and minimizes potential confusion.
For umpires, precision in tracking the ball count within an over will be paramount. Their signals will dictate the precise moment the field restrictions are eased, requiring meticulous attention to detail.

Streamlining Concussion Replacements: Prior Nomination for Parity
The ICC’s updated regulations for concussion replacements represent a significant step towards ensuring fairness and mitigating potential advantages, particularly for home teams. The core change is the requirement for teams to nominate and name specific concussion replacements to the match referee before the match commences.
Addressing the “Home Team Advantage”:
Previously, there was no pre-match nomination requirement, which could inadvertently benefit home teams. With a larger pool of local players potentially available outside the playing squad, a home team might have an easier time finding a like-for-like replacement on the fly compared to a touring side with a limited squad. The new rule aims to create “an even playing field between the participating teams by removing the home team advantage of a larger pool of players available.”
Categories of Nomination:
To ensure a structured approach to replacements, teams are advised to nominate one player for each of the following five categories:
- One wicketkeeper
- One batter
- One seam bowler
- One spin bowler
- One all-rounder
This categorization helps in the principle of “like-for-like” replacements, ensuring that a team suffering a concussion can substitute with a player whose primary skillset aligns with the injured player’s role.
Flexibility for Associate Member Teams:
The ICC recognizes the logistical challenges faced by Associate Member teams, especially when playing overseas, where their player pool might be significantly restricted. To cater to these circumstances, the regulations offer considerable flexibility:
- Multi-Category Nomination: A single player can be nominated for more than one category. For example, a versatile all-rounder could be listed as both a batter replacement and a seam bowler replacement.
- Batter as Wicketkeeper: A team can nominate a batter as a replacement wicketkeeper. However, the ultimate discretion lies with the match referee. While the referee may require the nominated batter to keep wickets if used in that role, they may also allow another player in the starting XI to keep wicket instead. This balances the need for like-for-like replacement with practical team management. The ICC emphasizes, “The purpose is a like-for-like replacement, not to try to gain an advantage with another batter.”
- Players Outside the Squad: Crucially, there has never been a requirement for concussion replacements to be restricted to the playing squad. This remains true. Teams can nominate “anyone who is eligible/qualified to play for them.” For home teams, this means potentially drawing from a wider pool of domestic players. For away teams, while generally limited to the touring squad, if eligible players are available in the country they are playing, they can be considered for nomination.
The Overarching Principle: Referee’s Discretion and Like-for-Like Replacement:
Despite the structured nomination process, the “over-riding principle of a like-for-like concussion replacement still applies.” The match referee retains significant discretion in assessing the circumstances at the time of a concussion and determining if a nominated replacement is “near enough like-for-like to the injured player.” This ensures that the spirit of fair play is maintained, and teams do not use the replacement rule to gain an unfair strategic advantage.
In exceptional circumstances, the match referee may even consider a replacement player who is outside the pre-nominated list, provided it aligns with the like-for-like principle. This demonstrates the ICC’s commitment to prioritizing player welfare while maintaining competitive balance.

Saliva on the Ball: Reinforcing Fair Play and Ball Integrity
While less extensive than the PowerPlay and concussion replacement changes, the ICC has introduced a critical clarification regarding the use of saliva on the ball. The key point is: “If any substance, including saliva, is used to change the condition of the ball, it is mandatory for the ball to be replaced.”
Preventing Strategic Misuse:
This amendment directly addresses a potential loophole. In the past, if a ball was deemed to have been illegally altered (e.g., through the application of saliva), it might have simply been cleaned or, in some cases, replaced at the umpire’s discretion. The new rule makes replacement mandatory.
The critical insight behind this change is to prevent teams from intentionally using saliva to alter the ball’s condition with the aim of forcing its replacement. The ICC’s statement highlights this: “Circumstances could arise whereby a team wants to change the ball and deliberately applies saliva to get it replaced. This new clause can prevent the ball from being automatically changed under these circumstances.
” By making replacement mandatory only when saliva is used to change the condition (implying an illegal alteration), it disincentivizes deliberate misuse aimed at getting a new ball under favorable circumstances. The onus remains on the officials to determine if the application of saliva was indeed an attempt to illegally alter the ball’s condition.

as it continues to captivate audiences worldwide. The implementation on July 10, 2025, will usher in a new phase of tactical considerations and operational precision for teams and officials alike. The staggered implementation, with Women’s playing conditions to be updated later, also highlights a deliberate and phased approach to these significant regulatory shifts.
(FAQs)
The International Cricket Council (ICC) has announced significant changes to the Playing Conditions for Men’s Twenty20 Internationals, effective from July 10, 2025. These updates primarily concern PowerPlay calculations, concussion replacements, and the use of saliva on the ball. Here’s a comprehensive guide to understanding these new regulations.
General Information
Q1: When do these new playing conditions come into effect? A1: These new playing conditions for Men’s T20 Internationals will officially come into effect from July 10, 2025.
Q2: Do these changes apply to Women’s T20 Internationals as well? A2: No, not immediately. These specific changes apply only to Men’s T20 Internationals. The ICC has stated that Women’s playing conditions will be updated separately, with an expected timeline of October.
Q3: What are the main areas of change in these new playing conditions? A3: The key areas of change are: * Revised calculations for PowerPlay overs in shortened matches. * New regulations for the nomination and use of concussion replacements. * A clarification regarding the mandatory replacement of the ball if saliva is used to change its condition.
PowerPlay Rule Changes
Q4: What is the fundamental change in how PowerPlay overs are calculated now? A4: The fundamental change is that the length of the PowerPlay will now be rounded to the nearest ball, instead of to the nearest over. This ensures the PowerPlay more accurately maintains its proportion of the total innings length, especially in shortened matches.
Q5: Why was this change to PowerPlay calculations necessary? A5: Previously, rounding to the nearest over in shortened matches could lead to significant variations in the percentage of the innings covered by the PowerPlay (which is broadly meant to be 30%). This could disproportionately affect team strategies. Rounding to the nearest ball ensures the PowerPlay remains much closer to the 30% proportion consistently, regardless of the innings length.
Q6: Can you give an example of how the new PowerPlay calculation works in a shortened match? A6: Certainly. * Under the old rules: An 8-over innings would have two PowerPlay overs (25% of the innings), and a 9-over innings would have three PowerPlay overs (33.3% of the innings). * Under the new rules: * For an 8-over innings (48 balls), the PowerPlay will end after 2.2 overs (two overs and two balls), which is exactly 30% of 48 balls. * For a 9-over innings (54 balls), the PowerPlay will end after 2.4 overs (two overs and four balls), which is exactly 30% of 54 balls.
Q7: Has this “nearest ball” PowerPlay system been used before? A7: Yes, this system has been successfully used in the T20 Blast in England for many years. The ICC noted that it has “caused no difficulty for players or officials” there.
Q8: How will players and umpires manage a PowerPlay ending mid-over? A8: The umpire will make a clear signal at the precise ball mark within the over when the PowerPlay concludes. At this signal, fielders who were restricted within the 30-yard circle will be able to move to deeper positions outside the circle. Players will need to be aware of the ball count within an over to anticipate these transitions.
Concussion Replacement Updates
Q9: What is the main change regarding concussion replacements? A9: Teams are now required to nominate and name specific concussion replacement players to the match referee before the match has started.
Q10: Why was this pre-match nomination requirement introduced? A10: This change aims to create a more even playing field between participating teams by removing any potential “home team advantage.” Previously, a home team might have had access to a larger pool of players outside their immediate squad for last-minute replacements, which touring teams typically wouldn’t.
Q11: How many players need to be nominated as concussion replacements, and what categories do they fall into? A11: Teams are asked to nominate one player for each of the following five categories: * One wicketkeeper * One batter * One seam bowler * One spin bowler * One all-rounder
Q12: Can a team nominate the same player for more than one category? A12: Yes, teams can nominate the same player for multiple categories. For instance, a skilled all-rounder might be nominated as both a batter replacement and a seam bowler replacement.
Q13: What if a nominated all-rounder replaces a batter? Can they bowl? A13: The ICC emphasizes the “over-riding principle of a like-for-like concussion replacement.” If an all-rounder replaces a batter, the match referee will likely restrict them from bowling, as the replacement is intended to be for a batting role. The referee has discretion to ensure the replacement does not provide an unfair advantage.
Q14: Can a batter be nominated as a replacement wicketkeeper? How will this work? A14: Yes, a batter can be nominated as a replacement wicketkeeper. If this nominated batter is used as the replacement wicketkeeper, the match referee may determine that they must keep wicket. Alternatively, the referee may allow another player in the starting XI to keep wicket instead. This decision is entirely at the referee’s discretion, prioritizing the like-for-like principle rather than allowing a team to gain an advantage by having an additional batter without keeping duties.
Q15: Do the nominated concussion replacements have to be part of the initial playing squad? A15: No. There has never been a requirement for the concussion replacement to be restricted to the playing squad, and this still applies. Teams can nominate anyone who is eligible and qualified to play for them.
Q16: How does this rule specifically affect home teams versus away teams regarding nominations? A16: * Home Teams: It’s generally easier for home teams to nominate five specific players as they can draw from a wider pool of eligible players in the country, even those not in the match squad. If finding five distinct players is difficult, the same player can be nominated more than once. * Away Teams:
Touring squads are typically smaller (e.g., 14 players). It’s unlikely for away teams to have many eligible players outside their touring squad in the host country. In these cases, teams should nominate the 3 players not in the playing XI on the form, with two of them nominated twice. If a replacement is needed, it will be handled based on the like-for-like principle from the nominations. However, if eligible players are available outside the squad in the host country, they can be considered for nomination.
Q17: Can a match referee allow a player who wasn’t pre-nominated to be a concussion replacement? A17: Yes, under “exceptional circumstances,” the match referee (or their replacement) may consider a replacement player who is outside of the nominated replacements submitted by the team for the match. This is covered in the nomination form and reinforces the referee’s ultimate discretion in ensuring a like-for-like replacement based on the specific situation.
Saliva on the Ball
Q18: What is the new rule regarding the use of saliva on the ball? A18: The new rule states: “If any substance, including saliva, is used to change the condition of the ball, it is mandatory for the ball to be replaced.”
Q19: What is the purpose of making ball replacement mandatory if saliva is used to change its condition? A19: This clause is designed to prevent teams from intentionally using saliva to illegally alter the ball’s condition with the specific aim of getting it replaced. By making replacement mandatory only when saliva is used for altering the condition (implying an illegal act), it removes the incentive for teams to deliberately apply saliva to force a new ball under favorable circumstances. The focus remains on maintaining the integrity of the ball.
