In the main event, former lightweight and former junior lightweight champion Joel "El Cepillo" Casamayor (35-3-1, 21 KOs), from Miramar, Fla., by way of Guantanamo, Cuba, takes on top-rated lightweight contender Michael Katsidis (23-0, 20 KOs), from Toowoomba, Australia, in a scheduled 12-round contest. A crafty 12-year ring veteran, the 36-year old Casamayor has stood toe-to-toe with the best the lightweight division has to offer, including Acelino Freitas, Jose Luis Castillo and Diego Corrales; in October 2006, Casamayor defeated Corrales by split decision to earn the lightweight title. Michael Katsidis, is an exciting, all-action fighter - with 20 knockouts in 23 bouts, he's forged a reputation as one of the biggest, most relentless punchers in the lightweight division. Following a unanimous decision victory over Czar Amonsot in July 2007, Katsidis looks to overcome Casamayor at 135 pounds and catapult himself to stardom.

The evening's co-feature event is a super middleweight bout between ambitious contenders, as Librado Andrade (26-1, 20 KOs), from La Habra, Ca. squares off against Robert Stieglitz (31-1, 19 KOs) of Magdeburg, Germany. Scheduled for 12 rounds at the 168-pound limit, this title eliminator showdown is a showcase opportunity in a fluid division.
