Two of the biggest UFC 174 winners will collide in Bangor, Maine.
Bader (17-4) scored a dominant victory over former Strikeforce light heavyweight champion Rafael Cavalcante last Saturday as he won back-to-back fights for the first time since 2012. In his previous UFC appearance, the Ultimate Fighter season 8 winner defeated Anthony Perosh.
St. Preux (16-5) enters the Octagon riding an impressive five-fight win streak, capped off by a second-round submission victory over Ryan Jimmo in Vancouver. With only one loss over the last 14 bouts, OSP is unbeaten in the UFC with wins over Nikita Krylov, Cody Donovan, Gian Villante and Jimmo.
