The International Cricket Council (ICC) has announced a series of significant updates to the playing conditions for One Day Internationals (ODIs), set to take effect from July 2025. These changes aim to restore balance between bat and ball, enhance player safety, and introduce strategic depth to the 50-over format. This article explores the key modifications, including the revised two-ball rule, mandatory team composition requirements for concussion substitutions, and updates to fielding restrictions, along with their potential impact on the game.
The Two-Ball Rule: Phasing Out to a Single Ball After 34 Overs
One of the most transformative changes in ODI cricket is the revision to the two-ball rule, which has been in place since October 2011. Currently, ODI innings utilize two new balls—one from each end—for the entire 50 overs. This rule was introduced to maintain the condition of the white ball, reducing wear and tear and aiding visibility for batters, particularly under lights. However, it has been criticized for diminishing the role of reverse swing, making conditions more favorable for batters in the latter stages of the innings.
ICC New Rules 2025 Details
Starting July 2, 2025, with the Sri Lanka-Bangladesh ODI series, the ICC will implement a hybrid approach to the two-ball rule:
- Overs 1 to 34: Two new balls will continue to be used, one from each end, as is the current practice.
- After the 34th Over: Before the start of the 35th over, the fielding team will select one of the two balls (each 17 overs old) to use for the remaining 16 overs (35 to 50). The chosen ball will be used from both ends until the end of the innings, unless it needs to be replaced due to damage or loss.
- Reduced Matches: In matches reduced to 25 overs or fewer before the first innings begins, only one new ball will be used per innings.
- Replacement Balls: The unselected ball after the 34th over will be added to the pool of replacement balls, which can be used if the chosen ball becomes unfit for play. Replacement balls will be of similar condition to the one being replaced.
Rationale and Impact
The decision to revert to a single ball after 34 overs stems from a desire to reintroduce reverse swing, a skill that has been largely absent in ODIs since the introduction of the two-ball rule. Reverse swing, which occurs when a ball is older and worn, allows bowlers to generate movement in the air, providing a counterbalance to the batting dominance seen in modern ODIs, where scores of 350 have become commonplace. By allowing the fielding team to choose a ball after 17 overs of use, the ICC aims to create conditions where bowlers can exploit wear and tear, making the latter stages of the innings more competitive.
This change could significantly alter match dynamics:
- Bowling Strategies: Pace bowlers, particularly those skilled in reverse swing like Waqar Younis and Wasim Akram in the past, may regain prominence in the death overs. Spinners could also benefit from a worn ball that offers more grip and turn.
- Batting Challenges: Batters will face increased difficulty in the final 16 overs, as the older ball may move unpredictably, requiring greater skill and adaptability.
- Tactical Decisions: The choice of which ball to continue with after the 34th over introduces a new strategic element. Captains will need to assess the condition of both balls and consider factors like pitch conditions, bowler strengths, and opposition batting line-ups.
The ICC’s men’s cricket committee, chaired by Sourav Ganguly, initially considered switching to a single ball after 25 overs but settled on 34 overs to allow sufficient wear while maintaining balance. Feedback from member boards was sought by the end of April 2025, and the rule was formalized at the ICC’s annual general meeting in July 2025.
Mandatory Team Composition for Concussion Substitutions
Player safety remains a priority for the ICC, and the updated concussion substitution protocols reflect this commitment. Starting in July 2025, teams will be required to submit a list of five designated concussion replacement players to the match referee before each ODI match. These players must include:
- 1 Wicketkeeper
- 1 Batter
- 1 Seam Bowler
- 1 Spinner
- 1 All-Rounder
New Rule Details
- Like-for-Like Replacements: If a player suffers a concussion, only a like-for-like replacement from the pre-submitted list may enter the game. For example, a concussed batter can only be replaced by the designated batter from the list.
- Exceptional Circumstances: In rare cases where a concussion replacement is also injured, the match referee has the authority to allow an additional substitute outside the original five, ensuring flexibility while maintaining fairness.
- Pre-Match Submission: The requirement to declare these substitutes before the match ensures clarity and preparedness, reducing disputes during high-pressure situations.
Rationale and Impact
The tightened concussion rules aim to prioritize player safety while ensuring competitive integrity. By mandating a diverse set of replacements, the ICC ensures that teams cannot exploit substitutions to gain a tactical advantage (e.g., replacing a batter with a bowler to suit match conditions). This rule builds on earlier ICC protocols, such as the introduction of concussion substitutes in 2005, which replaced the controversial “Supersub” rule that disproportionately benefited the toss-winning team.
The impact of this rule includes:
- Enhanced Safety: Clear protocols reduce delays in managing concussions, ensuring players receive prompt attention.
- Strategic Planning: Teams must carefully select their five substitutes, balancing squad depth with the need for specific roles.
- Fairness: The like-for-like requirement prevents teams from manipulating substitutions to alter team balance mid-match.
This change has been widely discussed on platforms like X, with posts highlighting its significance alongside the two-ball rule.
Fielding Restrictions: No Major Overhaul, but Continued Relevance
While the ICC has not announced sweeping changes to fielding restrictions for 2025, the existing rules will interact with the new ball regulations, potentially amplifying their impact. Current ODI fielding restrictions, in place since 2015, are as follows:
- Mandatory Powerplay (Overs 1–10): A maximum of two fielders are allowed outside the 30-yard circle, encouraging aggressive batting and attacking field placements.
- Middle Overs (Overs 11–40): Up to four fielders can be placed outside the 30-yard circle, allowing a balance between attacking and defensive fields.
- Final Overs (Overs 41–50): Up to five fielders can be outside the 30-yard circle, enabling more defensive strategies to curb big hitting.
Interaction with the Single-Ball Rule
The shift to a single ball after 34 overs aligns closely with the transition from the middle overs to the final 10 overs, where fielding restrictions loosen. This synergy could enhance bowling strategies:
- Reverse Swing and Fielding: With a worn ball in play from overs 35 to 50, captains may opt for more attacking fields to exploit reverse swing, potentially placing fielders in catching positions like slips or short cover, even in the death overs.
- Death Over Tactics: The ability to use five fielders outside the circle in the final 10 overs, combined with a ball more likely to reverse swing, could make it harder for batters to score freely, potentially reducing the frequency of 350+ totals.
Additional Fielding Notes
The ICC has also maintained existing rules to prevent defensive fielding tactics:
- Bodyline Prevention: Only two fielders are allowed in the quadrant between square leg and long stop to prevent bodyline tactics.
- Stop Clock: The 60-second stop clock, already in place for ODIs and T20Is since June 2024, will continue to enforce timely over transitions, with penalties like an extra fielder inside the 30-yard circle for slow over-rates.
While no new fielding restrictions were explicitly announced for 2025, the interplay between the single-ball rule and existing powerplay regulations will likely influence captaincy decisions, particularly in the latter stages of the innings.
Other Notable Changes
In addition to the two-ball rule and concussion protocols, the ICC has introduced or refined other rules to enhance fairness and safety:
- DRS Enhancements: Teams retain their review if the decision is “umpire’s call” for LBW reviews, ensuring fairness in close calls. The DRS is now used across all formats, including T20Is.
- No-Ball Rules: A delivery that bounces more than once before reaching the popping crease or lands off the pitch is called a no-ball, tightening bowling discipline.
These changes, while not directly tied to the two-ball or concussion rules, contribute to a broader effort to modernize cricket and improve decision-making accuracy.
Potential Impact on ODI Cricket
The 2025 rule changes are poised to reshape ODI cricket in several ways:
- Restoring Balance: The single-ball rule after 34 overs aims to level the playing field between bat and ball, potentially leading to closer contests and fewer high-scoring games. This could make ODIs more appealing to fans who value strategic bowling.
- Increased Tactical Depth: The choice of ball and the management of concussion substitutes introduce new layers of strategy, requiring captains and coaches to plan meticulously.
- Player Safety: The concussion protocols reinforce the ICC’s commitment to player welfare, ensuring that injuries are handled promptly and fairly.
- Fan Engagement: By making the game more competitive and less predictable, these changes could enhance the spectator experience, particularly in the middle and death overs, which have often been criticized for being one-sided.
Conclusion
The ICC’s 2025 rule changes for ODIs represent a thoughtful attempt to address longstanding concerns about the format’s balance, safety, and excitement. The phased return to a single ball after 34 overs is a bold move to revive reverse swing and challenge batters in the latter stages of the innings.
The mandatory team composition for concussion substitutions ensures fairness and preparedness, while existing fielding restrictions complement these changes to create a more dynamic game.
As these rules take effect from July 2025, starting with the Sri Lanka-Bangladesh series, cricket fans can look forward to a refreshed ODI format that blends tradition with innovation.
