Burfict suffers concussion

Bengals LB Vontaze Burfict left Sunday's opener against Baltimore in the 2nd quarter with a concussion.  He suffered the injury when he hit Ravens QB Joe Flacco shortly before halftime and has been ruled out for the game.  Burfict will obviously need to go through the league protocol before returning now.  We'll see what his status is for Week 2.  Baltimore moved the ball much more easily on the Bengals D in the 2nd half without Burfict around.
