In front of a sold out crowd of 55,000, ten men plan to make the Octagon their stomping ground as UFC 129: St. Pierre vs. Shields takes place in Toronto, Ontario, Canada. In the main event, welterweight champion “Rush” Georges St. Pierre (21-2) puts his title on the line against former Strikeforce Middleweight Champion Jake Shields (26-4-1) who is currently on a six-year, 15-fight winning streak. “The Natural” Randy Couture (19-10) hopes to end his seasoned career with a superb performance when he challenges former light heavyweight champ “The Dragon” Lyoto Machida (16-2). In another 205lbs. affair, goliaths “The Janitor” Vladimir Matyushenko (25-5) and “The Hitman” Jason Brilz (18-3-1) step into the cage, and former WEC 155lbs. king “Smooth” Ben Henderson (11-2) makes his UFC debut against Jiu-Jitsu stand-out Mark Bocek (9-3). In the co-main event, the hometown favorite “The Machine” Mark Hominick (19-7) welcomes “Junior” José Aldo (17-1) with every intention of taking his newly acquired UFC featherweight title. While both Hominick and Aldo have the ability to bring fights to a screeching halt, putting a championship up for grabs guarantees that both men will go tooth-and-nail to ensure that title goes home with them.
