The UFC 178 fight card has received a pair of new bouts, as Donald Cerrone will meet Bobby Green in the co-main event. With Green taking that fight, James Krause has been tabbed to face his previous opponent, Jorge Masvidal.

Set for September 27 from Las Vegas, the event recently lost a main event between Jon Jones and Daniel Cormier for the light heavyweight title. Instead, Demetrious Johnson will defend his flyweight belt against Chris Cariaso.

Cerrone (24-6) was rumored for a meeting with current Bellator champion Eddie Alvarez in September, but will instead take on the red-hot Green (23-5), who has won each of his four UFC fights, including a win over Josh Thomson.

Green immediately started in on the Twitter warfare after the bout was announced, calling out “Cowboy.”

Krause (21-5) has won two of three with the promotion, while Masvidal (27-8) sports a 4-1 Octagon mark.
