UFC officials announced the new fight on Thursday.
Following a stunning loss to Johny Hendricks late last year, Jon Fitch finally returned in October and got back to his winning ways with an exciting performance over up and coming star Erick Silva.
Now the Dave Camarillo black belt will get to test his Brazilian Jiu-Jitsu against one of the best in the business.
Since moving to welterweight, Demian Maia has looked very impressive.
After a long run at 185lbs, the Brazilian grappling ace decided to drop down to 170lbs an test the waters there instead, and the results have definitely gone his way.
Thus far Maia has beaten Dong Hyun Kim and Rick Story in back-to-back fights, and now faces yet another stiff test in former welterweight title contender Jon Fitch.
The new bout between Fitch and Maia is the latest fight added to the growing UFC 156 card, which takes place Super Bowl weekend on Feb 2 in Las Vegas.
