Former England captain Alastair Cook has questioned the match referee's decision, during the 4th T20I between India and England, to allow Harshit Rana to replace Shivam Dube as a concussion substitute. According to ICC Guidelines, ‘The ICC match referee should ordinarily approve a concussion replacement request, if the player is a like-for-like player.' Rana's introduction proved to be a turning point, as he scalped three wickets for 33 runs, rattling England's middle and lower order just when the visitors seemed to be building momentum in their chase of 182.
