Louisville defeated Duke 78-69 on Saturday afternoon at the KFC Yum! Center.
Duke committed 18 turnovers in the loss with Grayson Allen recording a career-high six turnovers.
On a loose ball, Allen appears to have been smacked in the face by Louisville's Donovan Mitchell on his way off the ground.

Allen has committed several questionable incidents on the year. Earlier in the week, it looked like Allen shoved a Florida State coach on the sidelines but the coach later clarified that it was not a dirty play. Allen has served a one-game suspension for tripping an opponent.
