No clue. But if he felt he would lose the fight eventually anyways, this would be the perfect setup
All Sonnen would have to do is survive the first round. And he did that perfectly. Take AS down and lay there. Don't take any risks that would expose a neck or limb to get subbed. Just get through to the second round.
And then dive. or slip. or get caught. whatever. Just lose it in the second round
Chaels shady. I'm quite sure this is what happened. I'll be filing a grievance with SBR and hope they see this through
