Former champion Joel Casamayor has announced that he finally found a clear solution to Timothy Bradley's headbutts. The Cuban fighter is concerned with Bradley's past history of inflicting injuries on his opponents with headbutts. Casamayor would like to use a protective helmet during the fight. Bradley defends his WBO junior welterweight title against Casamayor on Saturday night at the MGM Grand in Las Vegas, as part of the Manny Pacquiao-Juan Manuel Marquez HBO pay-per-view undercard.
