Mitchell Santner Concussion Sub Controversy — MI Replace Spinner with All-Rounder
Mumbai Indians vs Chennai Super Kings
April 2026
Mumbai Indians' use of Shardul Thakur as concussion replacement for Mitchell Santner during their Wankhede match against CSK in April 2026 placed the IPL's like-for-like concussion-substitution rule under public scrutiny. Critics argued that an all-rounder for a frontline spinner was not a like-for-like swap. MI's coaching staff, led by Mahela Jayawardene, defended the call as procedurally correct.
