Former India captain Sunil Gavaskar and former opener of the Indian Test team, Aakash Chopra, called on the International Cricket Council (ICC) to probe claims by the Indian team and its skipper Virat Kohli about Australia's alleged misuse of the Decision Review System (DRS), which came to the fore after Steve Smith was seen seeking the dressing room's opinion on reviewing his dismissal during the 2nd Test. "When a board, which is a member of the ICC, raises a concern, it should be addressed by the ICC," Gavaskar told NDTV, backing BCCI's call for a probe. "If it isn't nipped in the bud by ICC, it could snowball into a major controversy," Aakash Chopra said.
