Pollack suffered a neck fracture on Sept. 17 of last season, against Cleveland. He missed the remainder of the season, and he underwent surgery to repair the fracture on Jan. 3 of this year.
His recovery is ongoing.
"David and the team agree that he is not physically ready to play this season," said head coach Marvin Lewis. "He is working extremely hard and will continue focusing his efforts on rehabilitating with our medical staff."
He currently is among 81 signed players on the team's offseason roster.
Pollack, who suffered no paralysis from the injury, was quickly able to resume normal activities outside of football, though he spent much of the fall and winter wearing a neck immobilization device, which he no longer requires.
Pollack, was the Bengals' top draft choice in 2005, selected 17th overall. He played in 14 games with five starts as a rookie, and was limited to two games last season.
"I'm grateful for my recovery to this point, and I'm working every day to get my full strength back," Pollack said. "Any final decision on football is still down the road for me."
