Two new bouts are slated for the four-bout televised main card.
In heavyweight action, Brazilian jiu-jitsu black belt Rolles Gracie (8-1), a onetime UFC fighter and recent ONE FC competitor, meets Dave Huckaba (20-5), who's won nine of his past 10 fights while competing primarily on California's regional circuit. Sixteen of his 20 wins have come via knockout.
In the first televised bout, undefeated lightweight prospect Justin Gaethje (8-0), who recently upset big-show vet Gesias Cavalcante at WSOF 2, takes on Brian Cobb (20-7), a former UFC and MFC fighter who's won five of his past six fights, including a WSOF 1 bout with Ronys Torres.
On the untelevised prelims, a previously reported bout between lightweights John Gunderson (34-14-2) and Dan Lauzon (16-4) has come company. The new addition includes undefeated middleweights Krasimir Mladenov (8-0) vs. Kendrick Miree (5-0).
