Referee approved it, why is there so much noise about it: Gavaskar on concussion sub

Sunil Gavaskar has said that he doesn't understand why there is so much noise around Yuzvendra Chahal replacing Ravindra Jadeja as concussion substitute in first T20I. "The match referee is an Australian. He is former Australia cricketer David Boon. He had no objection," Gavaskar said. Gavaskar added that anyone who goes out with the bat is an all-rounder for him.
