It really wasn't surprising to see him spending the open portion of the workout off to the side while teammates went through drills. That's because he remains under the team's concussion protocol until he passes the battery of tests that are required before he's allowed to practice or play again.
Coach Marvin Lewis confirmed earlier in the day during his weekly news conference that Green was still under the protocol.
One of five players who didn't practice, Green sat for his second straight Wednesday session. Last week, he missed a day of practice because of a right biceps deep bruise that knocked him out of the Week 16 Monday night win over Denver. With special padding on his arm, Green played through the injury in Sunday night's 27-17 loss at Pittsburgh.
He suffered the concussion in the fourth quarter of the game when he was hit in the head by Steelers safety Mike Mitchell immediately after fumbling a completion that had given the Bengals a first down. Green was one of two Bengals to suffer concussions in the game. Reserve running back and special teams standout Cedric Peerman also left the game concussed. Receiver Dane Sanzenbacher was put on the season-ending injured reserve Wednesday because of a concussion experienced in the game.
The Bengals also missed rookie receiver James Wright on Wednesday, meaning they were down to just four receivers during the practice: Brandon Tate, Greg Little, Mohamed Sanu and Cobi Hamilton, a wideout who recently was signed off Cincinnati's practice squad.
Here's the Bengals' complete Wednesday injury report:
WR Dane Sanzenbacher (placed on IR with a concussion)
Did not practice
WR A.J. Green (concussion)
TE Jermaine Gresham (back)
CB Leon Hall (veteran's day off)
RB Cedric Peerman (concussion)
WR James Wright (knee)
