Back in 2008, Alistair Overeem and Mirko Flipovic met at Dream 6 in an anticipated heavyweight bout with a plot twist ending. Overeem seemingly bested Cro Cop during the bout before he landed a devastating knee to the groin that brought about an unceremonious conclusion to the action.

Clearly in pain, CroCop was not allowed to resume the match under the recommendation of the ringside doctor. His corner later relayed to the announcers that Overeem's knee to the groin had temporarily lodged his right testicle into his body.

Given the history between them, Overeem doesn't expect Cro Cop to come calling for a rematch against him anytime soon.

"Actually, I don't think so, because he's got a bad memory of me. In the fight, if we're going to be honest, I beat him and I broke him mentally, and I think - when I see him out it's all good, it's all good - but he's the kind of a guy that holds a grudge from deep within, and I think that's still a little bit in there."

"I don't think so because for him I'm a headache. He knows that."
