Fresh of an RFA title-winning victory, Devin Clark is octagon-bound with his debut set for UFC Fight Night 91 in Sioux Falls, S.D.

UFC officials today announced via argusleader.com undefeated Clark (6-0 MMA, 0-0 UFC), a Sioux Falls native who recently captured the RFA light-heavyweight title (watch it above), will move down to middleweight and take on Alex Nicholson (6-2 MMA, 0-1 UFC) at the July 13 event at Denny Sanford Premier Center.

UFC Fight Night 91 is expected to air live on FOX Sports 1 with early prelims streaming on UFC Fight Pass. The bout order has not been finalized.

Clark extended his unbeaten streak to six earlier this month at RFA 37, which took place at Sanford Pentagon, just a few miles from UFC Fight Night 91’s host arena. After a wild exchange against Rafael Viana, he got the better of standup and wrestling exchanges. In the process, Viana suffered a finger injury that left him unable to answer the bell for the third round.

Clark has now finished four of his six pro opponents before the final bell. In a previous interview with MMAjunkie Radio, he said he wanted to capture titles in all the major MMA organizations.

Nicholson, meanwhile, looks to rebound after a submission loss to Misha Cirkunov in his UFC debut. The former heavyweight tapped to a neck crank at UFC Fight Night 82, which snapped a five-fight win streak on the regional circuit.

With the addition, the UFC Fight Night 91 card now includes:

Tim Boetsch vs. Josh Samman

Scott Holtzman vs. Cody Pfister

Keita Nakamura vs. Kyle Noke

Ben Nguyen vs. Louis Smolka

Devin Clark vs. Alex Nicholson
