Cards WR Michael Floyd will be in concussion protocol. Cleared on sideline but had headache Monday.
Related players: John Brown, Jaron Brown, J.J. Nelson
We'll know more about Floyd later in the week. If he can't go, John Brown would be next up against the Rams. Ironically, Brown had a concussion in preseason and also suffered from headaches. Jaron Brown was making a push for more snaps and could also have a more significant role.
