Sooner or later, a fighter has to lose the "0" in their record, unless their name is Rocky Marciano. Later tonight, two undefeated heavyweights will battle to keep their undefeated records alive. Calvin Brock (28-0, 22 KOs), of Charlotte, NC, takes on Timur Ibragimov (21-0-1, 13 KOs), originally from Uzbekistan. Brock, a rising star in the heavyweight ranks is looking to pick up a big win over Ibragimov and land a title shot in the near future. Ibragimov is not only looking to win big, he also wants to step out of the shadow of his cousin, Sultan Ibragimov, another undefeated heavyweight who is regarded as the better of the two cousins and gets a lot more attention from boxing experts and the media.

The battle of undefeated fighters does not end there. To start off the action, a pair of undefeated welterweight battle to make some noise in a division packed with big names and big money. Joel Julio (27-0, 24 KOs), from Monteria, Colombia, now living in Miami, Fla., takes on highly ranked Carlos Quintana (22-0, 18 KOs), from Moca, Puerto Rico.

Joel Julio has so much buzz around him and many have put a label on him as being the next breakout star in the sport. Every person in the sport knows Julio can hit, and since he began training with Buddy McGirt, he sharpened up his boxing skills and learned a few new tricks. It will be interesting to see how Julio performs under McGirt.

Quintana is no pushover, and even Main Events admits the fight could go either way. Quintana is unknown to many, but the guy can fight and hit. He demolished Edwin Cassiani in three rounds, the same man who stopped Luis Collazo in three rounds.

Both men are very active, only one will walk away with the win.
