Two former Strikeforce fighters will step inside the Octagon this September, as Bobby Green meets Jorge Masvidal at UFC 178. Officials announced the bout on Tuesday.

Set for September 27 from the MGM Grand Garden Arena in Las Vegas, the card features a main event between light heavyweight champion Jon Jones and Daniel Cormier. Former bantamweight champion Dominick Cruz will also be in action that night, along with a returning Cat Zingano.

Green (23-5) stepped up on short notice and defeated Josh Thomson this past weekend, improving his win streak to eight overall. He is 4-0 since joining the UFC.

Masvidal (27-8) improved to 5-1 in his last six with a finish of Daron Cruickshank on the same UFC on FOX 12 card from San Jose. His lone loss came to Rustam Khabilov. Masvidal was hoping to face Donald Cerrone in September.
