Indian spinner Ravichandran Ashwin has taken a dig at the Australian captain Steve Smith's over the DRS referral issue. "This is completely unheard of. The last time I thought that to happen was in an Under-10 game when my coach used to suggest where point fielders and cover fielders used to stand”, said Ashwin. Notably, Smith turned back and asked the dressing room if he could take a review which was a controversial move in the second Test match at Bengaluru.
