UFC 137 was originally supposed to feature a title fight between UFC welterweight champion Georges St-Pierre and Nick Diaz. Instead, Diaz took on a former two-division champion in B.J. Penn and gave him one of the biggest beatings of his 22-fight UFC career.
After the fight, Diaz called out St-Pierre, who was in attendance at the Mandalay Bay Events Center in Las Vegas.
Other fighters on the main card include Cheick Kongo, Matt Mitrione, Scott Jorgensen, Mirko Cro Cop, Roy Nelson and Hatsu Hioki.
This is what’s next for the winners of those bouts.
