As it turns out, there is a UFC welterweight willing to fight Mike Perry on short notice.

MMAjunkie today confirmed Alex Reyes(12-2 MMA, 0-0 UFC) is stepping in for the injured Thiago Alves (22-11 MMA, 14-8 UFC) to face Perry (10-1 MMA, 3-1 UFC) in the co-headliner of Saturday’s UFC Fight Night 116, which takes place Saturday at PPG Paints Arena in Pittsburgh.

Perry also announced the switch on his Twitter account.

The event airs on FS1 following an early prelim on UFC Fight Pass.

Reyes makes his octagon debut on the strength of a 12-fight win streak. A Team Oyama fighter, he returned to the cage in August after a two-year layoff and earned a first-round knockout of Gilbert Guardado.

Perry is coming off a second-round knockout of Jake Ellenberger at UFC Fight Night 106, which put him back in the win column after a decision loss to Alan Jouban at UFC on FOX 22.
