Somewhere along the way, the relationship between UFC Hall of Famers Matt Hughes and B.J. Penn turned from a bitter rivalry into a buddy flick.
The duo did their part to help build the first wave of Zuffa-era success with a memorable fight trilogy.
Penn, one of just three two-division champs in UFC history, went up in weight and stunned Hughes to win the UFC welterweight belt via first-round submission at UFC 46.
Hughes took the rematch at UFC 63 with a third-round TKO in Anaheim in one of the sport’s most memorable comeback victories.
