He missed the remainder of the 2006 season, and he underwent surgery to repair the fracture on January 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 Lewism in the statement. "He is working extremely hard and will continue focusing his efforts on rehabilitating with our medical staff."
No roster move is necessary at this point regarding Pollack. He currently is among 81 signed players on the team's offseason roster.
Pollack suffered the neck injury Sept. 17 as he made a hit on Cleveland running back Reuben Droughns. Pollack suffered no paralysis from the injury. He 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, from the University of Georgia, 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."
