UFC® lightweight champion BJ Penn looks to be the first fighter in history to hold two UFC championships at the same time when he faces Georges St-Pierre for the UFC welterweight championship; but the two champions aren’t the only ones with something to lose.

When Thiago Silva (6’1”/205 lbs., fighting out of Sao Paulo, Brazil) meets Lyoto Machida (6’1”/205 lbs., fighting out of Belem, Brazil), both fighters will put their undefeated records and top-contender statuses on the line. Machida, 13-0, outlasted former UFC light heavyweight champion Tito Ortiz in his last bout and has posted five UFC wins in his career. The two-time Brazilian Karate champion is known for his unorthodox style and counter-striking, and he’ll need all of those skills against the devastating offense of Thiago Silva. The 26-year-old Brazilian jiu-jitsu black belt with the 13-0 record has put away every UFC opponent, earning TKO wins against Houston Alexander, Tomasz Drwal and James Irvin along with a submission due to strikes victory against Antonio Mendes.

Las Vegas, Nevada’s Stephan Bonnar (6’4”/205 lbs) will always be remembered for the phenomenal fight he had with Forrest Griffin in the original finale of The Ultimate Fighter®, but more recently the 31-year-old is on a two-fight win streak with a TKO win over Eric Schafer and a submission victory against Mike Nickels. Bonnar will need his all of his Octagon™ experience when he fights the undefeated Jon Jones (6’4”/205 lbs., fighting out of Endicott, N.Y.). The Rochester, N.Y. native is coming off a decision win against Andre Gusmao in his UFC debut and will face his toughest opponent to date in Bonnar. The 21-year-old Jones is a former junior college national wrestling champion and is now 7-0 in his mixed martial arts career.
