Ito Smith left the Rams game on Sunday after getting run over by linebacker Cory Littleton on a failed 3rd-and-10 pass. He laid flat on the field, then slowly got up before the cart came out.
Smith already missed time this season with a concussion. If he suffered another concussion, he will likely be out for an extended period of time. Players typically do not return to the game after leaving the field on a cart.
Ito was unusually high here in pass protection. It does not seem like Littleton went low or was intentionally trying to hit Smith in the helmet.
