Edgar has agreed to face Chan Sung Jung in the main event of the Dec. 21 fight card, according to multiple people with knowledge of the pending booking following a report from ESPN.com. UFC President Dana White also confirmed the switch on the Rich Eisen Show.
Jung lost his originally scheduled opponent for UFC Busan when onetime title challenger Brian Ortega suffered a torn ACL and was forced to withdraw from the event in South Korea. The search led to Edgar, who is five months removed from a loss to featherweight champ Max Holloway at UFC 240.
