UFC 137 plays host to many memorable battles this weekend.
The pay-per-view event takes place at the Mandalay Bay Events Center in Las Vegas this Saturday night, where a pivotal welterweight tilt between former champions Nick Diaz and BJ Penn will headline.
Also on the card, two heavyweight notables will meet in the crux of their UFC careers, as both Roy Nelson and the legendary Mirko Cro Cop meet in a “loser leaves town” kind of bout.
Both men are coming off of back-to-back losses in lackluster performances, albeit against the upper echelon of the division.
So will these two fare against one another come this Saturday?
