Legendary Indian opener Sunil Gavaskar slammed the concussion substitute rule, which allows for like-for-like replacements during a game, as rewarding incompetence. His remarks came after Team India wicketkeeper Rishabh Pant suffered a foot injury on Day 1 of the ongoing fourth Test against England in Manchester.The 27-year-old underwent scans overnight and was diagnosed with a fractured toe, ruling him out of the remainder of the series.When asked about substitutes for an injury during a match, Gavaskar took to the concussion substitution rule in place.He said on the Sony Sports Network [4:45]:"I've always felt that you are giving a like-for-like substitute for incompetence. If you are not good enough to play short-pitched bowling, don't play Test cricket; go and play tennis or golf. You are giving a like-for-like substitute for somebody who can't play the short ball and gets hit."Despite the injury, Pant came out to bat hobbled on Day 2 and added valuable runs to take India past the 350-run mark. His 75-ball 54 helped the side finish on a competitive 358 in their first innings."There has to be a substitute" - Sunil Gavaskar on Rishabh Pant's injurySunil Gavaskar believes instances like Rishabh Pant's situation warrant allowances for an injury substitution during a game. While Dhruv Jurel is allowed to keep wickets instead of Pant, he or another reserve cannot bat in place of the swashbuckling left-hander."Here, it is a clear injury (Pant); there has to be a substitute. I want some sort of committee appointed to take a call on this. There is a cricket committee, ICC has a cricket committee, but at the moment that's headed by Sourav Ganguly, the ICC chairman is Jay Shah, and the ICC CEO is Sanjog Gupta," said Gavaskar (via the aforementioned source).He added:"So we don't want a situation for the media here in particular and in Australia to say, 'Oh, because it's an Indian situation, they have started to do that'. So, let it be a totally different committee to look at these injuries, maybe with doctors, etc., and let that committee come to a call."Pant will miss the series finale at the Oval but can bat in the second innings should it be required. Meanwhile, the ongoing fourth Test is well-poised with the hosts racing to 225/2 in response to India's 358 at the end of Day 2.
