The Ultimate Fighting Championship on Friday officially released the full fight card for its Jan. 31 event, featuring a welterweight title defense by champion Georges St. Pierre in a mega-fight with UFC lightweight champion B.J. Penn.

A win for Penn would make him the first champion in UFC history to hold titles in two weight classes concurrently. Besides a future title defense against Thiago Alves, a St. Pierre victory could possibly line-up another dual champion bout, with current middleweight champion Anderson Silva.

The main card also features a light heavyweight bout between Top 10 ranked fighters Lyoto Machida and Thiago Silva and an expected barnburner between Nate Diaz and Clay Guida.

The preliminary card features many UFC veterans, but is most notedly, and perhaps surprisingly, highlighted by a welterweight clash between Jon Fitch, just one fight removed from a challenge to St. Pierre’s title, against Japanese fighter Akihiro Gono.
