UFC Fight Night 100 results: Darren Stewart stops Francimar Barroso after accidental headbutt

SAO PAULO – Darren Stewart walked out of the octagon successful after his UFC debut. But it could be short lived as an accidental headbutt led to the TKO of Brazilian opponent Francimar Barroso.

The light heavyweight bout opened up the preliminary card of today’s UFC Fight Night 100 event at Ibirapuera Gymnasium in Sao Paulo. It streamed on UFC Fight Pass ahead of the rest of the card on FS1.

Stewart (8-0 MMA, 1-0 UFC) quickly showed off a gameplan of clinching to minimize Barroso’s (18-6 MMA, 3-3 UFC) space and look to put the fight on the floor.

The awkward ending came as Barroso attempted to find space. Stewart charged forward in the clinch, only to have his head smack into Barroso’s face. Barroso reacted by complaining and covering his face as Stewart swarmed with punches as his foe covered up on the ground.

The referee jumped in to call an end to the bout at the 1:34 mark of Round 1, awarding Stewart the controversial TKO victory to a shower of boos from the Brazilian faithful.
