FWIW, I heard Dan Patrick say on his show yesterday that he'd spoken with someone in the locker room at the time of the alleged altercation. According to his source, there was a brief, verbal and animated exchange between two (maybe three?) players.
There was no "brawl," and that after the verbal exchange the players involved exchanged high fives and hugs.
Again, for FWIW but I believe Patrick. He's about the last objective sports journalist left.
