Watch UFC 163 Aldo Vs Jung Live Stream Online

Anthony Pettis was originally slated to meet Aldo on Saturday, but an injury forced the lightweight out of his 145-pound debut. Undefeated since joining the UFC roster, Jung was quickly named Pettis' replacement.

In addition to the featherweight championship, former light heavyweight champion Lyoto Machida will make his way to the Octagon for a bout with Phil Davis. Despite winning back-to-back fights that were labeled title-shot eliminators, Machida is still in search of a rematch with 205-pound champion Jon Jones.
