Mark Smith ACL Tear: UFC Referee Finishes Fight, Gets Carried Out

Mark Smith tore his ACL during UFC 324 while refereeing Gautier vs Pulyaev. The 52-year-old veteran finished all 15 minutes on a blown knee, then was carried out of T-Mobile Arena. Dana White compared it to Bruce Buffer’s 2011 injury—the only other non-fighter ACL tear he’s witnessed in UFC history.
