M.S.Dhoni walks into the field with all the technology installed in his brain. He can see Hot-Spot with naked eye, he can assume the ball tracker too.
During the encounter between Mumbai Indians vs Rising Pune Supergiant, M.S.Dhoni went for DRS jokingly, though there is no DRS available in IPL.
On the 2nd ball of 15th over, Imran Tahir got Pollard in front of the wickets but the umpire, S Ravi had to make a call if it was bat or pad first. He went for bat first and gave it not-out. Replays confirmed it was pad first. That was plumb and Pollard survived. Dhoni calls for the DRS showed his sense of humour.
Here's the video:
