A pair of bouts have been made official for UFC 171, as Thiago Silva takes on Ovince St. Preux and Bubba McDaniel meets Tor Troeng.

Set for March 15 from the American Airlines Center, the event features a main event between UFC light heavyweight champion Jon Jones and Glover Teixeira.

Silva (16-3) will be returning following a victory over Matt Hamill that pushed his UFC mark to 7-3. St. Preux (14-5), a former Tennessee Volunteer football player, won his second straight inside the Octagon by defeating Cody Donovan.

McDaniel (21-7) and Troeng (16-5) have each split their two UFC appearances since competing on The Ultimate Fighter 17.
