Detroit guard Kentavious Caldwell-Pope sprained his left knee in the third quarter in the Pistons' 91-89 exhibition loss to the Washington Wizards on Sunday.
Caldwell-Pope, a second-year player out of Georgia, fell underneath Washington's basket and needed assistance getting to the locker room. He did not return after scoring 12 points in 24 minutes.
Pistons coach Stan Van Gundy said Caldwell-Pope will be looked at when the team returns to Detroit.
