Miami quarterback Tyler Van Dyke was injured and doubtful to return against Duke on Saturday.
Van Dyke was hurt on a sack in the second quarter, and immediately grabbed his right shoulder before walking off the field and going into the locker room for X-Rays. Miami described it as an "upper body injury."
Headed into the game, Van Dyke and the Miami offense had struggled with regaining the form they had last season - when he emerged as the starter following an injury to D'Eriq King.
In six games entering Saturday, Van Dyke had thrown for 1,656 yards, nine touchdowns and four interceptions.
