Frank Mir is the Former UFC Heavy-Weight champion. Who had broken the current Champs Tim Sylvia's arm ( via armbar ) in a previous fight. He lost his Belt because he mangled his leg in a motorcycle accident. ( some old lady sideswiped him or something ) So he came back for his long awaited fight after injury and got pounded by Marcio Cruz who he was supposed to beat... =)
you can check out his or any fighter's mma win/loss record here at this website just do a search on his last name.
