Originally, Parisyan was set to face former Ultimate Fighter competitor Shamar Bailey in the headline fight, but injury has forced the Indiana native out of the bout, and Gunderson has opted to step in to replace him.
Parisyan’s management team at Apex Sports Agency confirmed the switch to MMAWeekly.com on Friday.
John Gunderson comes into the fight with Parisyan following a win over Team Alpha Male fighter Justin Buccholz at Superior Cage Combat in February.
The former UFC and IFL veteran will step up to 170lbs to challenge Parisyan in the main event.
