UFC 137: "Penn vs. Diaz" took place last night (Sat., Oct. 29, 2011) from the Mandalay Bay Events Center in Las Vegas, Nevada, featuring Stockton's own Nick Diaz representing the 209 by putting a beaten on the pride of Hilo, Hawaii, B.J. Penn, in a three-round, 15-minute war.
For his efforts -- and his mouth -- Diaz has been re-inserted into a welterweight title fight against Georges St. Pierre over the Super Bowl weekend early next year.
In other action, Roy Nelson sent Mirko Filipovic off to retirement with a third round technical knockout loss. Hatsu Hioki was successful in his UFC debut with a split decision win over George Roop, while Scott Jorgensen took care of business against Jeff Curran.
