Tank Dell, wide receiver for the Houston Texans, is being evaluated for a concussion during the second half of Sunday's game against the Falcons. Dell hit his head hard on the turf in the second quarter and will be examined in the locker room to determine if he can return. If he is unable to return, Dell will finish the game with three receptions for 57 yards on four targets, as well as two carries for minus-4 yards.
