UFC 94 St-Pierre vs Penn 2 PosterThe UFC has officially announced UFC 94: St-Pierre vs. Penn 2, which features the highly anticipated rematch between welterweight title-holder Georges St-Pierre and lightweight champion BJ Penn.

In their first meeting in early-2006 St-Pierre topped Penn via split decision to become the top contender in the 170-pound division, and ultimately captured the title, while Penn dropped down to 155-pounds and earned the lightweight championship.

Now, nearly three years removed from their first meeting, the pair of top UFC fighters will meet again, but this time the welterweight championship will be on the line when they clash on January 31st in Las Vegas.

“This may be the most anticipated rematch in UFC history,” said Dana White, UFC President. “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. Now these two champions meet again with a lot of pride and St-Pierre’s title on the line. This fight will be talked about for years to come.”

“I’m very honored to fight BJ Penn and very excited because it’s the fight that everybody wants to see, including myself,” said St-Pierre. “It will be one of the most anticipated fights in UFC history, and I’m glad and humbled to be a part of it.”

“For that fight, I was at a point in my career where I didn’t prepare as well as I should have,” Penn said. “During the second and third round I realized that I ran into someone that wanted it more than I did…Now, I’m very prepared to go five rounds.”

Top light heavyweight contenders Lyoto Machida and Thiago Silva are also expected to clash at UFC 94, with more bouts expected to be officially confirmed soon.
