Thompson (hamstring) is questionable to return to Sunday's game against the Ravens, Patrik Walker of the Cowboys' official site reports.
Thompson sustained the injury during the second quarter, and after being checked on in the blue medical tent, the veteran safety made his way to the locker room, where he'll undergo further tests to determine whether he can return to Sunday's game. Alijah Clark should see more snaps on defense for as long as Thompson is out of the game.
