Lucas Brennan It would appear that Legacy Fighting Alliance (LFA) has locked in a multi-fight amateur contract with Lucas Brennan. The Ultimate Fighting Championship (UFC) feeder organization has added the son of MMA royalty to their ranks. Many of the competitors from LFA make their way to other promotions as their fighting prowess grow. The world's most famous mixed martial arts promotion, the UFC, often picks up competitors from the organization. With that in mind, it would appear that 17-year-old Lucas Brennan has reached a milestone in his fighting career by signing with the promotion. Lucas Brennan is son to UFC veteran and mixed martial arts legend Chris Brennan and will compete as an amateur for three fights under the LFA banner before going pro. Brennan made his debut in the amateur circuit in August, earning a submission victory under the Xtreme Knockout Amateur Series promotion. For more MMA news click here.
