Also, unbeaten Olympic bronze medalist Eumir Marcial (3-0, 1 KO) will take on Ricardo Villalba (20-7-1, 8 KOs) in an eight-round middleweight scrap, heavyweight Dainier Peró (2-0, 2 KOs), younger brother of world-rated Lenier Peró, will clash with Daniel Zavala (2-1-2, 0 KOs) over four rounds, while David Whitmire makes his pro debut against Texan Keith Foreman (0-0, 1 NC) in a four-round super welterweight duel.
