Stewart's win at UFC Sao Paulo overturned due to accidental foul

Darren Stewart is going to have to wait a little longer for his first UFC win.

The Englishman appeared to make a successful debut at UFC Fight Night 100 this past Saturday when he defeated Francimar Barroso by first-round TKO. However, the Brazilian MMA Athletic Commission (CABMMA) has overturned the result to a no-contest after reviewing an accidental foul that occurred during the bout.

Footage showed that Stewart's head connected with Barroso's cheek as he pushed him against the cage, and the Brazilian fighter immediately reacted as if he was injured by the illegal headbutt. Referee Eduardo Herdy did not see Barroso's reaction and he waved the fight off shortly after as Stewart took Barroso down and finished him with ground-and-pound.

CABMMA issued a statement Tuesday via Guilherme Cruz of MMA Fighting that stated the foul did have a direct impact on the outcome of the bout and was only discounted because Herdy was at a disadvantageous angle to properly call the action.

CABMMA COO Cristiano Sampaio also noted in the statement that instant replay was not used properly, making it impossible to evaluate the result on fight night.

Stewart's professional record remains at 7-0, while Barroso officially avoids a second straight loss.
