10 Toughest UFC Heavyweights Active Today

4. Mark Hunt

http://www.youtube.com/watch?v=v17ZtAOEP8w Do we even need to explain this one? Mark Hunt is a man who just won't quit. Literally. When the UFC/Zuffa acquired Pride, they didn't really have any interest in letting Hunt fight, and offered to buy out his contract. Hunt would have none of it. He refused the buyout and insisted on fighting. So they gave Hunt a fight, and he lost. That had him on a six fight losing streak. It was assumed he was done. Then he took another fight, and won. And another. And another. He was knocking guys out left right and centre. Twitter campaigns popped up asking Dana White to give Hunt a title shot. The UFC finally had to take notice and put him in a title eliminator with Junior Dos Santos. While he lost that, he still bounced back and fought in one of, if not the, greatest heavyweight bouts of all time with Antonio Silva that ended in a draw. The fight saw both men battered and bloody after smashing each other for five rounds. Hunt, who is 40, just signed a new contact for six more fights that will take him to retirement. He'll be around 43 years old when he's done, and will go down as one of the toughest fighters to ever set foot in the octagon.
