Yeah, it was Tamim. I think the whole team was pumped up by that time. Apparently, Tamim asked Wade to get off the field quickly coz "there was business left to be done". Hence the hand gesture. God knows what Wade said back.
For the violation above and his repeated debate with the umpires re: frequent gloves change by Aussie batsmen in the morning session earned him 1 demerit point. He already had 1 demerit point from the 2nd test against SL. So, he is now 2 DM points away to be banned for 1 Test or 2 ODI/T20. (Source:
