The Cincinnati Bengals placed All-Pro defensive tackle Geno Atkins on injured reserve.

Atkins leads the Bengals with six sacks and has 29 tackles. Last season, Atkins led all NFL interior linemen with 12.5 sacks. He has played in the last two Pro Bowls.

They signed free agent defensive tackle Christo Bilukidi to the roster. He was a sixth-round draft choice of the Oakland Raiders last season and played in 13 games, with 12 tackles. He played in the Raiders' first five games this season, with four tackles, including a sack. He was waived by the Raiders on Oct. 23.

The Bengals signed rookie linebacker Bruce Taylor to the practice squad.
