Abel Trujillo is out of this month’s UFC Fight Night 94 event, and a replacement search is underway.

A UFC official today confirmed with MMAjunkie that Trujillo (15-6 MMA, 6-2 UFC) has suffered an undisclosed injury and been forced out of his bout against fellow lightweight Evan Dunham (17-6 MMA, 10-6 UFC).

UFC Fight Night 94 takes place Sept. 17 at State Farm Arena in Hidalgo, Texas. It airs on FS1 following early prelims on UFC Fight Pass.

Dunham vs. Trujillo was slated for the main card.

Trujillo, who’s approaching his five-year anniversary with the UFC, is 5-1 over his past six fights, and against Dunham, he was looking for his fourth straight victory. It’s not clear when he’ll return to the cage.

Dunham, who once won four UFC fight-night bonuses in a seven-bout span, is also looking for his fourth straight win after a recent career resurgence.
