Already a High Injury Risk at 36%, McCoy' Injury Risk jumped even higher after a head injury on Sunday. McCoy appeared to tweak his ankle but ended up being ruled out due to a concussion. He remains in concussion protocol and is in a race against the close to clear ahead of the Bills' tough Week Eight matchup with the Patriots. McCoy hasn't suffered a concussion in recent years, but he did miss four games in 2012 with a very serious concussion. That could complicate his recovery a bit, as we know repeat head injuries increase the overall concern going forward.
