According to a new report on the official website of Demian Maia, the renowned grappler will next compete inside the UFC’s Octagon on February 21 during UFC 95 against former World Extreme Cagefighting competitor Chael Sonnen.

Maia is quickly earning a reputation as one of the top middleweight fighters in the world by accumulating a perfect 4-0 record since being signed by the UFC. His wins inside the Octagon over Ryan Jensen, Ed Herman, Jason MacDonald, and Nate Quarry have allowed the jiu-jitsu black belt to improve his overall MMA record to 9-0.

He will look to keep his perfect record intact against Sonnen, who will be beginning his second tour of duty in the UFC following stints with the WEC and BodogFIGHT.

Sonnen is 21-9-1 and trains out of Matt Lindland’s Team Quest in Portland, Oregon. After recording a unanimous decision victory over former WEC middleweight champion Paulo Filho at WEC 36 in November, Sonnen improved his record to 7-1 over the course of his last eight fights.

The part-time realtor is getting the opportunity to improve on his lifetime 1-2 record in the UFC after being transferred over from the WEC, which is owned by Zuffa, the parent company of the UFC. Zuffa decided to transfer several of its top middleweight and light heavyweight competitors over to the UFC after discontinuing the WEC’s 185 and 205 pound divisions.

UFC 95 will emanate from the O2 Arena in London, England and will be headlined by the lightweight debut of Diego Sanchez as he takes on former UFC lightweight title challenger Joe Stevenson. Both Sanchez and Stevenson are former winners of The Ultimate Fighter reality television series on Spike TV.

Other reported matchups for UFC 95 include Nathan Marquardt vs. Wilson Gouveia, Junior dos Santos vs. Stefan Struve, Shannon Gugerty vs. Jeff Lawson, and Justin Buchholz vs. Terry Etim.
