ICC introduces new rule changes across all formats

The International Cricket Council (ICC) has introduced a series of rule changes that will apply to all three formats of men’s international cricket — Tests, One Day Internationals (ODIs), and Twenty20 Internationals (T20Is).

The new rules include modifications to the use of balls in ODIs and updated concussion substitute protocols.

ODI changes

Under the current ICC rule, a new ball is used from each end for 25 overs. Going forward, both balls will be used up to the 34th over. From the 35th over onwards, teams must choose one of the two balls to continue with until the end of the innings.

For matches reduced to 25 overs or fewer, only one ball will be used throughout. 

According to the ICC, the new law will help bowlers, especially by enabling reverse swing in the death overs, which has become rare under the existing rule due to consistently newer balls.

Concussion substitutes

As per the new policy, captains must now submit a list of five designated concussion substitutes before the toss. The list must include; one batter, one all-rounder, one wicketkeeper, one fast bowler, and one spinner.

Previously, teams could name concussion substitutes during a match without prior declaration.

The new ICC regulations will take effect from June 17 for Test matches, July 2 for ODIs, and July 10 for T20 Internationals.

‘Bunny hops illegal’

In a separate rule update, the ICC, in collaboration with the Marylebone Cricket Club (MCC), has decided to prohibit the controversial ‘bunny-hop’ style of boundary catches, according to reports.

Catches in which a fielder jumps from beyond the boundary without first touching the ground inside the field of play — and redirects the ball while airborne — will now be ruled illegal.

For a catch to be considered valid, the fielder must have made initial contact with the ball while grounded inside the field of play.

However, fielders who initially touch the ball inside the field, step outside due to momentum, and then return to complete the catch, will still be permitted under the law.

While this rule will officially come into effect from October 2026, it will be reflected in ICC playing conditions starting next week.
