UFC 94. St. Pierre vs. Penn II Officially Announced

The Ultimate Fighting Championship today officially announced its Jan. 31 "UFC 94: St. Pierre vs. Penn II" event, which takes place Jan. 31 at the MGM Grand Garden Arena in Las Vegas.

The main event features a UFC welterweight championship fight between current title-holder Georges St. Pierre and UFC lightweight champion B.J. Penn.

The fight, which airs live on pay per view, is a rematch of their March 2006 bout in which St. Pierre earned a split-decision win.

With a victory in the rematch, Penn could become the first fighter in UFC history to simultaneously hold belts in two different weight classes.

"This may be the most anticipated rematch in UFC history," UFC President Dana White stated in today's press release. "Their first fight was an epic battle of two of the best pound-for-pound fighters in the sport. After that fight, St. Pierre would go on to win the UFC world welterweight title, and Penn would go on to win the UFC world lightweight title."

Although not officially announced, a light heavyweight bout between Lyoto Machida and Thiago Silva is expected to take place at UFC 94. Karo Parisyan will look to reclaim contender's status against Dong Hyun Kim, and Stephan Bonnar also meets Jon Jones on the card.
