Mickey Rourke fought in and won a professional boxing match last weekend in Moscow. People were impressed when the 62-year-old actor knocked out someone half his age in the ring. The Daily Mail reports that Rourke's opponent, Elliot Seymour is a "homeless drifter" who trains at Rourke's gym, and who was paid to lose. However, Seymour disputes the rumors that the fight was fixed. But, the 29-year-old boxer says he was stiffed a large part of his earnings. Seymour tells TMZ he was supposed to be paid $15k to step in the ring with Rourke ... but only got $10k.
