It's an unwritten rule of cricket that batsmen don't run overthrows if the ball has deflected off their body or clothing while making their ground on a throw.
On the final ball of the 23rd over, bowled by James Faulkner, Rohit pushed to mid-off where it was fielded by Warner.
The batsman took a few steps out of his crease contemplating a single before planting his bat behind the crease. Warner's throw appeared to miss the batsman but Brad Haddin, perhaps distracted by Rohit's proximity, missed it and the Indians took off for a single.
Glenn Maxwell was first on the scene to remonstrate with Rohit before Warner arrived from his fielding position, speaking as he walked past.
A reply from Rohit caused Warner to stop and the umpires were quickly onto the scene to separate the pair, with Suresh Raina trying to interject himself between Rohit and Warner. The conversation continued into the next over with the new bowler, Shane Watson, also exchanging words.
