UFC 137 goes down this Saturday night, sporting a new main event between welterweight contenders BJ Penn and Nick Diaz. A former dual division UFC champion, Penn is 1-0-1 in his current stint at welterweight, having taken out Matt Hughes dramatically and fought Jon Fitch to a draw. Diaz vacated his Strikeforce belt to return to the UFC for a shot at welterweight champ Georges St-Pierre, but lost that shot after failing to follow through on several of his media duties. The two men share similar fighting styles and philosophies and their impending tilt promises to be a scrap.
Check out the video below, courtesy MMAInterviews, to hear who the pros believe will take the fight and way. The fight will go down at the Mandalay Bay Events Center in Las Vegas, Nevada and, as always, FightLine will be back on the night with live, ongoing coverage of the event.
