Khamzat Chimaev will now wrestle former UFC middleweight champion Chris Weidman after Colby Covington withdrew from Saturday’s RAF 14 main event in Abu Dhabi, the promotion announced Monday.
RAF did not disclose what led to Covington’s withdrawal, but Chimaev took a shot at the former UFC interim welterweight champion on social media. Covington was on a five-match winning streak in RAF but recently tapped out to a rear-naked choke in grappling against UFC bantamweight Raul Rosas Jr.
The RAF light heavyweight crossover championship will be on the line for Chimaev vs. Weidman at the Etihad Arena in Abu Dhabi.
Chimaev was dominant in four straight wrestling matches since June, defeating Dillon Danis, Tyron Woodley, Gilbert Burns and Robbie Lawler. He now takes on Weidman while awaiting his next UFC assignment.
Weidman appeared once under the RAF banner, losing a decision to Covington back in May. That was his first competition since losing a grappling match to Patrick Downey in mid-2025.
