Here’s some footage from the altercation between Katto and Ghambir from the third session on Day 1.

I’ve watched it a bunch of times and from my observations there was a bit of argy bargy that almost leads to a run-out escallates when Ghambir try’s to tell Billy that Katich was cheating by getting in his way. Katto responds with “that’s f’ucking shit man”. Brett Lee comes past and throws a few inaudible words of support behind his NSW captain, then Katto and Ghambir are at it again and you hear Simon utter “F’uck off mate”. Billy steps in when it looks like they might up the ante, and Michael Clarke comes in to calm the farm. Clarke has to make a pretty solid effort of holding back Katich who by this time looks like he wants to punch on.
