Well I would like to think that the "working" days are over in MMA, but that doesn't mean that he did take a fall. I am sure he was not that disappointed in losing, so now he can concentrate on making the fight with Fedor now that he isn't the UFC champ. At the same time, I think Brock's punching power is just so strong, that most of his punches that glance off or barely hit the mark are still enough to knock someone off balance, as he did against both Mir and Herring in previous fights.
