BURBANK, Calif. (AP) -- If Junior Dos Santos ever ended up in the same ring as Wladimir Klitschko, the UFC's heavyweight champion is pretty sure he knows how it would end.
Dos Santos thinks he could knock out the biggest man in boxing.
It's not just bravado from the unbeaten Dos Santos, who has emerged as one of mixed martial arts' top fighters with an all-around game built on a foundation of stand-up fighting. The Brazilian bruiser is among the best boxers in his sport, and he's confident he could hold his own with Klitschko, the three-belt heavyweight champ.
But Dos Santos doesn't plan to start a boxing career any time soon. He's preparing for his next title defense, a rematch with Cain Velasquez at UFC 155 in December.
