10 Toughest Bastards In UFC History

9. Chris Leben

He may have an MMA record of one less in every three fights - 11 defeats in his 33 contests - but that's not an indicator of how tough Chris Leben is.

It took 17 fights before somebody could actually KO Leben, with that opponent being the legendary Anderson Silva.

In a mixed bag of a career, Leben managed to make a reputation for himself as a man who could take a ridiculous amount of punishment and then turn around a lay an opponent out with one single punch.

Since a run of four consecutive defeats brought his UFC career to an end in 2013, more recently Chris Leben has turned his attention to the world of professional bare knuckle boxing. And that, ladies and gentleman, is an extremely scary prospect for anybody unfortunate to go up against this famed heavy hitter.
