EVENT: Lyoto Machida v. Randy Couture (UFC 129)
COMPLEX SAYS: At the age of 47, "The Natural" just couldn't retire from the Octagon. Dude needed some sort of sign to convince that it was the right time to hang it up. So, when he met Lyoto Machida in UFC 129, a damaging front kick to the dome may have been the sign he was looking for. Ughk, the foul (or sweet, word to Rex Ryan) taste of defeet.
21. Lyoto Machida KO's Randy Couture
