KANSAS CITY, Mo. -- An MRI confirmed that Kansas City Chiefs defensive end Alex Okafor suffered a torn pectoral muscle in Sunday's win against the Broncos, a source told ESPN's Josina Anderson.
Okafor was injured while sacking Denver quarterback Drew Lock. He immediately left the game and didn't return.
Okafor has five sacks this season, which ranks fourth on the Chiefs. Third on that list is defensive end Emmanuel Ogbah (5.5), but he is also done for the season after tearing a pectoral muscle last month.
Without Okafor, the Chiefs are down to three true defensive ends: Frank Clark, Tanoh Kpassagnon and Demone Harris.
