Toronto, Ontario, Canada gets its first taste of UFC action when the Rogers Centre hosts UFC 129: St. Pierre vs. Shields this Saturday. In the main event, title challenger Jake Shields (26-4-1) hopes to keep his six-year winning streak going when he faces current 170lbs. king “Rush” Georges St. Pierre (21-2) for the coveted welterweight title. The headlining superfight is directly supported by “Junior” José Aldo (17-1) returning from the injured list to face “The Machine” Mark Hominick (19-7) with his featherweight title up for grabs. Nebraska’s favorite fighter “The Hitman” Jason Brilz (18-3-1) enters the cage opposite International Fight League (IFL) veteran “The Janitor” Vladimir Matyushenko (25-5) and Toronto’s native son Mark Bocek (9-3) plans to give former WEC champ “Smooth” Ben Henderson (11-2) a rude welcoming in his UFC debut. In the midst of the action, history will be made as “The Natural” Randy Couture (19-11) enters the Octagon, allegedly for the last time, against the always calm but equally dangerous “The Dragon” Lyoto Machida (16-2). While the UFC Hall of Famer Couture will always be loved and admired for his accomplishments both in and outside the sport, ending his career on the highest possible note with a victory may prove difficult against Machida, who himself looks to get back on the road towards title contention.
