MJ Practiced Today with No issues, Cam Jordan's Ankle Better

That's dangerous thinking. I seem to recall giving questionable guys the week off against Seattle because they were only 7-9 and finding ourselves out of the playoffs. There's no telling how any given game is going to go... got to put your best players on the field if they're able to play.

1) Multiple concussions in three weeks
2) Rookie year for a player who appears to have many (violent) playing years ahead
3) Plays a concussion-prone position

The dangerous thinking is equating Vaccaro's situation with the injuries that sidelined Thomas, Jenkins and Ivory for the Seattle game.
