Ravens safety Ed Reed was sidelined from Thursday’s practice with a neck injury, according to Aaron Wilson of National Football Post.

“I would think that every quarterback, when they see Ed Reed back there, they have to be a little sharper,” defensive coordinator Greg Mattison said. “And they sometimes can’t take the gambles that you would take, because he may be thinking exactly the same way that quarterback is thinking and he’s standing there.”

Reed’s ailing injury could keep him out of the Ravens matchup against the Bengals on Sunday. The Ravens could use him more in the playoffs, but they still have a chance to win the division with a Steelers loss to Cleveland.
