Brock Lesnar took one last kick to his stomach and crumpled at the side of the cage, unable to fight back when Alistair Overeem pounced.
Lesnar had been finished by a 6-foot-5 Dutch kick boxer in the first round at UFC 141. A few minutes later, the UFC's former heavyweight champion finished his own meteoric mixed martial arts career.
Lesnar retired from the UFC after Overeem stopped him with one vicious kick to the body at 2:26 of the first round in their heavyweight bout Friday night, leaving the UFC heading into 2012 without its biggest pay-per-view star.
"This is the last time you'll see me in the octagon," Lesnar said.
