Here's the play-by-play of the entire bout from Brent Brookhouse's live blog of the event:
Fedor Emelianenko vs. Dan Henderson - Round 1 - Fedor comes out throwing hard. Henderson landing heavy and backing him off. They're trading big shots and Henderson pushes Fedor into the cage. Fedor's right eye is already swollen and bleeding. Fedor defends a takedown by grabbing the fence. Hendo throws a bomb on the exit that just misses. Fedor unloads a right hand that just misses now. Gus says it landed, it did not. Now an overhand right does land. Fedor follows him to the ground. Henderson sweeps and lands some huge punches and Fedor is out! Dan Henderson wins by TKO (punches), round 1. One or two may have been to the back of the head but it was in the heat of the moment. HUGE moment for Henderson.
