This incident happened on the 5th delivery of the 10th over, where Charith Asalanka was adjudged LBW out. The batter went for the review and ultimately the third umpire also adjudged the Lankan out. However, when the onfield umpire Jayaraman Madanagopal was asked to stay with his decision and signal 'out' at the very moment Mohammad Siraj and Kuldeep were running behind the umpire with the drinks for their teammates.
Both of them raised their fingers while they were crossing behind the umpire. First Siraj raised his finger with the umpire while Kuldeep also followed the pacer with his finger raised. However, Kuldeep was nudged by mistake by the umpire's elbow. However, fortunately, the nudge wasn't very heavy and Kuldeep managed to stay on his feet.
