MGM Grand, Las Vegas - On Saturday night, Jason Litzau pulled off one of the biggest upsets of the year when he fought his way to a ten round split decision victory over Celstino Caballero, a 13-1 favorite coming into the fight.

BoxingScene.com was advised by promoter Lou DiBella that Caballero does not have a rematch clause to face Litzau. Earlier in the week, Litzau was as high as a 15-1 underdog at some offshore sportsbooks. DiBella said that a rematch between the two is possible.

"We don't have a rematch clause but we are going to look into making a rematch," DiBella told BoxingScene at the post fight press conference.
