UFC 92: The Ultimate 2008

UFC 92: The Ultimate 2008 was a mixed martial arts event by the Ultimate Fighting Championship (UFC) held on December 27, 2008 at the MGM Grand Garden Arena in Las Vegas, Nevada.

The main event featured number-one contender Rashad Evans winning the UFC Light Heavyweight Championship from Forrest Griffin. The referee stopped the fight due to a series of strikes from Evans in the third round.

The first co-main event saw former UFC Heavyweight Champion Frank Mir score a second-round technical knockout of former PRIDE heavyweight champion and then current UFC Interim Heavyweight Champion Antonio Rodrigo Nogueira. Mir claimed the UFC Interim Heavyweight Championship from Nogueira and earned the right to face then UFC Heavyweight Champion Brock Lesnar in a title-unification bout in early 2009.

The other co-main event was a fight between former UFC Light-heavyweight champion Quinton Jackson and former PRIDE Middleweight champion Wanderlei Silva. Jackson avenged two earlier losses to Silva by knocking Silva out in the first round.
