UFC 116 Carwin beats up Lesnar in Round 1 but can't finish him in the ref's opinion

Carwin traps Lesnar's right jab and throws a flurry of punches starting with a left jab and a right uppercut. This forces Lesnar to retreat quickly and cover up while Carwin continues to throw three left uppercuts that land to Lesnar's head. At the end of the round, Lesnar's cornerman tells him "you don't want to throw down with someone like him...you need to regroup."  While Carwin's cornerman tells him to "stay in the center of the ring. Relax."
