But there could be worse news ahead.
There is no timetable for Stewart's return. Bill Koch of The Cincinnati Enqurier reports that Stewart could be out longer than one week, meaning he could miss the Bearcats' critical game against Louisville next Friday.
Stewart is third in the Big East with five sacks and the unquestioned leader on the Cincinnati defense. But more than that, he is the unquestioned leader of this team, hoping to make yet another run at the Big East title. If he is out for an extended period of time, the No. 21 Bearcats will have a tougher time getting there.
Brandon Mills would be the obvious choice to enter the starting lineup.
