Both fighters are coming off brutal losses last December at the "UFC Fight For The Troops" event in Fayetteville, North Carolina. Yoshida was knocked unconcious on his feet then dropped again by Josh Koscheck, while Wolff was left with a huge swell on his head as the recipient of Ben Saunders' devastating knees from the clinch.
Wolff (7-3) of Hawaii is a one-time EliteXC competitor and holds a win over 2-time UFC competitor Chad Reiner.
Yoshida (10-3) had a nine-fight win streak before his loss to Koscheck. In his UFC debut at UFC 84 in May 2008, Yoshida finished War Machine "Jon Koppenhaver" with an anaconda choke.
