Werdum made the announcement about his return on Tuesday at his gym in California, where he answered fan questions and talked about his new deal via Ustream.
The Brazilian Jiu-Jitsu ace confirmed that he has signed a new 4-fight deal with the UFC that kicks off Feb 4 in Las Vegas.
Werdum also confirmed independently when speaking with MMAWeekly.com‘s Erik Fontanez on Tuesday that he has verbally agreed to face Roy Nelson on the card.
The bout between Werdum and Nelson will definitely be on the main card for the show, but current rumors have placed the fight as a co-main event for the show.
The headliner will feature an interim welterweight title fight between Carlos Condit and Nick Diaz.
MMAWeekly.com will have a featured video interview with Werdum later on Tuesday.
