Brock Lesnar vs Frank Mir — Fight recap

Frank Mir submitted Brock Lesnar via submission in round one at 2:30, reclaiming the UFC heavyweight title at UFC 81. Lesnar controlled the opening exchanges, landing 16 of 24 significant strikes (66%) with his head strikes and securing his lone takedown attempt at a perfect 100%, accumulating 1:07 of control time.

However, Mir's patience paid dividends as he weathered the initial onslaught and capitalized on positioning, converting one of his three submission attempts into a fight-ending armbar that forced Lesnar to tap.
