IPL 2025: The Board of Control for Cricket in India (BCCI) has introduced several key rule changes for IPL 2025, as reported by Cricbuzz on March 23 (Sunday).
The updated regulations include concussion substitutes, adjustments to retired-out scenarios, and new guidelines for team sheet announcements. Additionally, the fourth umpire's role has been expanded significantly.

A like-for-like replacement can be chosen from the nominated substitutes in case of a concussion. If a wicketkeeper sustains a concussion, the replacement can be selected from the available squad. If an overseas player suffers a concussion and the team has already used its four overseas slots, the replacement must be an Indian player from the substitutes.
For matches impacted by rain or interruptions, a retired batter will now count as a wicket lost in the Duckworth-Lewis-Stern (DLS) calculations. This ensures greater fairness in target adjustments for the chasing team.
Team sheets will now be exchanged after the toss. Captains will carry separate sheets for their batting and bowling sides. Once the toss result is determined, the captains will hand over their respective sheets to the match referee, while team managers exchange them with each other and provide copies to the Assistant Venue Manager.
The fourth umpire will now have increased responsibilities, including:
