A highly anticipated flyweight matchup has been scratched from UFC Fight Night 49, as Tim Elliott (10-5 MMA, 2-3 UFC) has been forced to withdraw from a planned bout with Wilson Reis (17-5 MMA, 1-1 UFC).

MMAjunkie today learned of the withdrawal from a source close to the fighter who spoke on the condition of anonymity because he is not authorized to publicly discuss such matters. UFC officials are now seeking a replacement opponent for Reis.

Featuring a lightweight matchup between Benson Henderson and Rafael dos Anjos, UFC Fight Night 49 takes place August 23 at BOK Center in Tulsa, Okla. The event’s main card airs on FOX Sports 1 following preliminary bouts on FOX Sports 2 and UFC Fight Pass.

Reis, who drops from bantamweight to flyweight for the contest, made his UFC debut in September of this past year after competing in other organizations around the globe since turning professional in 2007. He has split his first two octagon appearances, defeating Ivan Menjivar by unanimous decision at UFC 165 and losing a narrow split decision to Iuri Alcantara at UFC Fight Night 36 in February.

Elliott was also looking to return to the win column. The 27-year-old has dropped his past two bouts; however, those defeats came to former and future flyweight title challengers Joseph Benavidez, Ali Bagautinov and John Dodson. His successes under the UFC banner have seen him defeat Louis Gaudinot and Jared Papazian.

A timetable for his return wasn’t immediately established.

With the change, the latest UFC Fight Night 49 lineup now includes:

MAIN CARD (FOX Sports 1, 10 p.m. ET)

Rafael dos Anjos vs. Benson Henderson

Jordan Mein vs. Mike Pyle
