UFC heavyweight champion Junior Dos Santos added fuel to the promotional fire when he said Frank Mir's heart was suspect in fights.
But fans shouldn't take it as a sign that Dos Santos is abandoning his nice-guy rep for that of a trash-talker. The way he sees it, he's an honest guy, and he'll continue to be.
"I wasn't talking bad about him," Dos Santos today told MMAjunkie.com. "I just gave my opinion. I have nothing personal against him."
