Legacy FC has put together an intriguing card with some familiar names for its March 21 return to AXS TV. Legacy FC 29, which takes place at Hard Rock Hotel and Casino in Tulsa, Okla., features a light-heavyweight headliner between Paul Buentello  (33-15) and Myron Dennis  (9-2). The organization’s vacant title is on the line. Buentello, a former UFC and Strikeforce title challenger, recently made his 205-pound debut and knocked out James McSweeney. He now looks for his fifth straight victory when he meets Dennis, a onetime Bellator fighter who makes his Legacy FC debut after winning four of his past five fights. As MMAjunkie recently reported , Legacy FC 29 also marks the promotional debut of “The Ultimate Fighter 12″ winner Jonathan Brookins  (13-6), a former lightweight and featherweight who heads all the way down to flyweight for a bout with fellow 125 pounder Cody Fuller  (10-7)
