Baltimore Ravens wide receiver suffered a right foot injury against the San Diego Chargers on Sunday.
The veteran fell to the turf in the third quarter and immediately pointed at his foot and signaled for the training staff to come help him. Two trainers helped him up and more or less carried to the locker room. Smith was unable to put any weight on the foot.
