More details on the brawl came out via FrontRowBrian, a ticket industry operative who also operates as something of a guerilla MMA reporter. He has a good relationship with Sonnen so that could well be his source:
Chael and Wand were fighting. Chael was on top of Wand. Wand’s coach comes and punches Chael in the back of the head. He’s okay though
@FrontRowBrian1 hr #TUFBrazil has been an clusterfuck from literally day 1. Horrendous move by to even do this. Chael/Wand fighting not even most shocking part
Details RE Chael/Wand fight. Wand threw looping punch, Chael ducked, double legged him. GNP. Then Wand’s goon punched Chael bk of head
And then a bunch of people swarmed in and broke the whole thing up.
No. His head is sore though. RT
@iamKokoD: @FrontRowBrian @MMAG33K was Chael knocked out by the cheap shot?
The coach who punched Chael Sonnen in the back of the head was Andre Dida. Used to coach Shogun too. Fought in Dream.
