In a controversial moment during the IPL match between Mumbai Indians (MI) and Chennai Super Kings (CSK), MI opted to use Shardul Thakur as a concussion substitute for Mitchell Santner. MI head coach Mahela Jayawardene explained that Santner suffered a head injury while attempting a catch, leading to dizziness and necessitating the substitution. The incident occurred on the fifth ball of the 17th over when Santner made a diving catch but hit his head on the ground. Replays support Jayawardene's claim of Santner's injury. Despite the substitution, MI faced a heavy defeat, bowled out for just 104 runs while chasing CSK's total of 208 runs. Sanju Samson's stellar performance, scoring an unbeaten 101 runs, played a crucial role in CSK's victory, while Akeal Hosein's four-wicket haul dismantled MI's batting order.
