The International Cricket Council (ICC) is going to introduce some significant cricket rule changes across all formats. They are introducing the changes from the 2025-26 season of cricket. The changes in the rules for ODIs and T20Is will be introduced in July, whereas the Test match rules will be altered from June, before the World Test Championship cycle of 2025–27 begins. Significant Rule Changes on the Horizon Two new balls have been utilized in ODIs since 2011, but this did not help spinners and prevented reverse swing. Therefore, the ICC will revert to the use of a single ball for ODIs, just like they used to do prior to 2011. According to the new directives: "There will be two new balls for overs 1 to 34. After over 34 is completed and prior to the start of over 35, the fielding team will choose one of the two balls to be used for over 35 to 50. The chosen ball will be used at both ends for the remainder of the match (unless it needs to be changed)." Also Read | Why Only the Ambanis Sit on Sofas Near the IPL Boundary? This means, the team can select a ball of their choice (from the two used for the first 34 overs) for the remaining 16 overs. Incase, if the game is affected by rain and overs are reduced to 25 overs or fewer, each side will get a new single ball to play with. The concussion substitutes rules have also been altered. Teams need to nominate five players beforehand to act as concussion substitutes: a batter, a wicketkeeper, a spinner, a pacer, and an all-rounder. If a player is injured during the match, the referee can bring in a different player as a substitute, provided that player has similar skills to the injured player. There will be alterations in a few other regulations as well, such as when the Decision Review System (DRS) can be employed and how catches or boundary saves close to the ropes should be dealt with. But ICC has not given complete information regarding these yet, and we can expect them shortly. Some of the rules will remain unchanged. For instance, if a ball gets harmed during a match, it will be replaced with a ball in an equivalent state. Additionally, to prevent teams from abusing the ball, the ball utilized between overs 35 and 50 will be inspected thoroughly while replacing it.
