The story behind BJ and Frankie

Dana White explains how BJ Penn vs Frankie Edgar came to be.

Unless you've been living under a rock, you've probably heard that 'The Progidy', 'The Prodidy' ' The Prodigy' BJ Penn and his nemesis, Frankie Edgar, have signed on to be the coaches of The Ultimate Fighter season 19.

After taking an extended hiatus from fighting after his 3 round drubbing at the hands of one of MMA's finest young talents, Rory MacDonald, Penn returns to face a familiar opponent in a completely new weight class.

Dropping to 145lbs will be a challenge for the often physically limited Hawaiian, but as we've seen time and time again, a motivated BJ Penn can beat just about anyone.

UFC President Dana White seems pretty fired up about the recent events as well. In fact, he came on UFC Tonight to explain how this seemingly improbable match up came to be.
