Junior dos Santos has been a wrecking ball since joining the UFC, running off eight consecutive wins and taking the heavyweight title from the previously undefeated Cain Velasquez in his last fight. The champ faces a new challenge at UFC 146 in Frank Mir, but first he's taking on all comers on Yahoo! Sports.
The heavyweight champ will join Yahoo! Sports analyst Kevin Iole for a live chat on Thursday at 9 p.m. ET/6 p.m. PT. You got a question for 'Cigano'? Don't be shy.
