William Knight stays at heavyweight; Devin Clark elevates to fight him at UFC on ESPN 34

William Knight will stick around at heavyweight at least a little bit longer.

At UFC on ESPN 34, Knight (11-3 MMA, 3-2 UFC) will take on Devin Clark (12-6 MMA, 6-6 UFC) in a three-round heavyweight bout. The event takes place at the UFC Apex in Las Vegas and airs on ESPN/ESPN+.

Two people with knowledge of the matchup informed MMA Junkie of the booking Thursday, but asked to remain anonymous as the promotion has yet to make an official announcement.

Knight, 33, competed at heavyweight in his most recent outing, a split decision loss to Maxim Grishin at UFC 271 in February. However, the elevation up a division was a bit unexpected, as Knight missed the light heavyweight limit by 12 pounds. The bout was allowed to continue at heavyweight, as Grishin agreed. The loss snapped a two-fight winning streak for Knight that included victories over Fabio Cherant and Alonzo Menifield.

Clark, 31, was scheduled to compete at UFC on ESPN 34, but his opponent was never made public. Usually a light heavyweight, Clark is set to make his heavyweight debut off back-to-back losses suffered against Anthony Smith and Ion Cutelaba. Prior to the current skid, Clark won back-to-back fights against Dequan Townsend and the aforementioned Menifield.
