There are reports circulating out of Argentina that Diego Chaves has pulled out of his fight against Tim Bradley on December 13th at the Cosmopolitan in Las Vegas.

But according to the head of Top Rank Inc., which is promoting this event - "We talked to the manager, it's Chaves' brother causing trouble. We have a signed contract. There's no problem, at all."

Bradley-Chaves is part of an HBO tripleheader that also has a junior welterweight match-up between Mauricio Herrera and Jose Benavides and a bout between Matt Korobov and Andy Lee for the vacant WBO middleweight title.
