The UFC is looking for a new main event for its first card of August.
Umar Nurmagomedov is out of his scheduled headliner against Cory Sandhagen, sources confirmed Wednesday with ESPN. The UFC is seeking a new opponent for Sandhagen, a top bantamweight contender, for the Aug. 5 card at Bridgestone Arena in Nashville, Tennessee.
Nurmagomedov has a shoulder injury and is scheduled for surgery next week, according to his manager, Ali Abdelaziz of Dominance MMA.
ESPN has Sandhagen ranked No. 5 in the world at 135 pounds.
Sandhagen (16-4), 31, has won two straight, most recently a split decision victory over Marlon "Chito" Vera in March. His three losses since 2018 have come to former or current UFC champions.
Nurmagomedov's withdrawal was first reported by The Schmo.
