Lightweight contender Jose Felix (30-1-1, 25 KOs) returns to action this weekend versus Marcos Leonardo Jimenez. Their scheduled 10-riund bout tops a Top Rank-promoted show at the Sportsmen's Lodge in the Los Angeles suburb of Studio City, Calif. , airing live on UniMas (Saturday, 11:00 p.m. ET/PT). 

Leonardo 'Lenny' Zappavigna faces Ramon Ayala in the evening's co-main event, scheduled for eight rounds. 

The Australian-born Zappavigna (33-2, 23 KOs) has won his last eight bouts in a row since suffering back-to-back losses to Miguel Vazquez and Ammeth Diaz in 2011.

Ayala (23-4-1, 11 KOs) has lost his last two fights over a span of three years. He was stopped by Omar Figueroa in 2012 and was stopped after four rounds to Chris Van Heerden on May 13.

Unbeaten light heavyweight Oleksandr Gvozdyk (6-0, 4 KOs) will fight Francisco Sierra (27-8-1, 24 KOs) in an eight round bout. The 2012 Olympic Bronze Medalist is trained by Robert Garcia.
