Jeremy Stephens and Rony Jason will square off, just a month later than originally planned.
The two featherweights have been added to UFC Fight Night 32 in November from Brazil. It joins a lineup featuring Vitor Belfort and Dan Henderson in the main event.
Stephens (21-9) snapped a three-fight losing skid by earning a decision over Estevan Payan this past May. That was his first fight at featherweight after a career spent in the lightweight division.
Jason (13-3) has won three straight, including the title of Ultimate Fighter: Brazil last year. He submitted Mike Wilkinson in his most recent fight.
Bleacher Report first reported news of the fight.
