Offensive lineman Mike Pollak was placed on the Active/Physically Unable to Perform list by the Cincinnati Bengals with a knee injury. He will count against the team's roster limit and can be activated to practice as soon as he is cleared medically.

Pollak, an experienced guard who is expected to also compete for the starting center job, hopes to return to the field in time for the Bengals' first training camp practice Thursday.

He joins defensive tackle Geno Atkins and cornerback Leon Hall on the physically unable to perform list for the Bengals.
