A.J. Green still under NFL concussion protocol and not expected to practice Wednesday

Cincinnati Bengals wide receiver A.J. Green remains under concussion protocols, according to Cincinnati Enquirer beat writer Paul Dehner Jr. and Bengals.com's Geoff Hobson. Green suffered the injury during a fourth-quarter fumble against the Pittsburgh Steelers on the second impact from Steelers safety Mike Mitchell.

Head coach Marvin Lewis confirmed the protocol during Wednesday's presser -- and nothing else (which you could interpret either way.

Green hasn't been entirely durable this year, missing three games and most of a fourth due to a toe injury. A hard shot against the Denver Broncos led to a deep bicep bruise and a decoy role for most of that game -- though he was able to play the following week during the regular season finale in Pittsburgh.

It's no use speculating how this impacts Sunday's games... largely because of the uncertain nature with concussions. However, if he's unable this Sunday against the Indianapolis Colts, the Bengals will only have Mohamed Sanu, Brandon Tate, Dane Sanzenbacher and James Wright, who has been out with a knee issue since Week 13, at receiver.
