Timothy Bradley and Diego Chaves both made weight for their HBO main event on Saturday night, with Bradley coming in at 145.8 pounds, and Argentina's Chaves at 146½, both under the 147-pound limit.
Bradley (31-1, 12 KO) is the favorite in the fight, but Chaves (23-2, 19 KO) is at least somewhat of a danger to Bradley. The underdog can punch, and has given Keith Thurman and Brandon Rios difficult nights in varying ways, though he also did lose to both of them.
