E of CSKBiggest IPL win for Tihas And an umpire’s decision at the center of controversy on the day of Mumbai Indians’ biggest defeat.

On this day, Shardul Thakur was not in the starting XI of Mumbai Indians. But he is seen batting. Now many people may have a question IPLSo there is the rule of ‘Impact Sub’, Shardul Thakur fell under that rule, what is there to question or debate about it? But the fact is that Shardul did not enter the field as an impact sub. Mumbai Indians replace Ghazanfar with Danesh Malebar as impact sub. However, how Shardul entered the field is where the real debate lies.

In the 17th over of Mumbai’s bowling innings, Santner hit a full-length dive to catch Karthik Sharma. But while catching this catch, he injured his shoulder. Santner was seen writhing in pain with a hand on his shoulder, adding to Mumbai Indians’ anxiety. He also left the field. He is later seen carrying an ice pack in the dressing room of the Paltans. Instead of Santner, Shardul was fielded as a concussion sub. But the question arises whether concussion sub is available only when a cricketer suffers a head injury.

Before using the concussion sub, the medical report of the injured cricketer has to go to the match referee. He takes all due care to ensure that the team does not get an extra advantage, by allowing a player who is of the same skill level as the injured player to replace that player. From that side, both Shardul and Santner are bowling all-rounders. No doubt about that. But in this case, the injury was on Santner’s shoulder and not on his head, so the question arises as to what logic and on what basis Shardul was allowed to come down as a concussion sub.

However, in this case, many claim that it is not always necessary to get hit on the head for concussion. A hard blow to any part of the body can cause damage to the head, causing dizziness. The counter-argument is that the same is true of Santner.
