CINCINNATI -- Bengals defensive tackle Tank Johnson left the game against the Dolphins after limping off with an injured right knee.

Johnson stayed on his back and grabbed his right knee after a play early in the third quarter Sunday. He got up and winced as he limped off with assistance, then went to the locker room for examination.

The Bengals' defensive line already was missing end Antwan Odom, serving the second game in his four-game suspension for violating the league's policy on performance-enhancing substances.
