Nate Diaz, the season five winner of the Spike TV reality series “The Ultimate Fighter,” appears set to return to the Octagon at UFC 94 on January 31 at the MGM Grand Garden Arena in Las Vegas against fellow lightweight standout Clay Guida.

The UFC has yet to officially announce the bout, however, the news comes courtesy of, a website owned and operated by Diaz’s manager and trainer, Cesar Gracie.

Diaz and Guida were originally expected to fight during a UFC event in December but the fight never materialized due to a foot injury sustained by Guida during a unanimous decision victory against Mac Danzig at UFC Fight Night 15 in September. Like Diaz, Danzig is also a former winner of “The Ultimate Fighter.”

The victory improved Guida’s record to 24-9 and cemented his standing as one of the UFC’s most highly regarded fighters. Thanks in large part to his relentless style of fighting, the 27-year old Chicago native holds notable victories in his career against Josh Thomson, Bart Palaszewski, and Marcus Aurelio.

Diaz, the younger brother of EliteXC lightweight competitor Nick Diaz, has not fought since a split decision victory over Josh Neer at UFN 15. The victory moved the 24-year old’s record to 10-2 overall with his record in the UFC improving to 5-0.

A jiu-jitsu brown belt under Gracie, Diaz has defeated Manny Gamburyan, Junior Assuncao, Alvin Robinson, and Kurt Pellegrino in addition to Neer during his year and a half tenure in the UFC.

UFC 94 will be headlined by welterweight champion Georges St. Pierre defending his title against reigning UFC lightweight champion B.J. Penn. Additionally, light heavyweight bouts between Lyoto Machida vs. Thiago Silva and Stephan Bonnar vs. Jon Jones are scheduled as well.
