Paulo Costa Out, Khamzat Chimaev Gets New UFC 294 Opponent

Less than 24 hours after announcing UFC 294 had a new main event, the promotion has reported that the October 21 fight card also has a new co-main event.

UFC 294, which takes place at Etihad Arena in Abu Dhabi, initially had Khamzat Chimaev facing Paulo Costa in the co-main event. That fight fell through after Costa was ruled out after he underwent elbow surgery a few weeks ago.
