Cincinnati Bengals defensive tackle Geno Atkins has been sidelined against Miami because of a knee injury and has been ruled out for the rest of the game.

Atkins was slow to get up following a play in the second quarter Thursday, then walked off the field with assistance from two teammates. He came into the game with a team-high five sacks.

The Bengals were already without middle linebacker Rey Maualuga and safety Taylor Mays, who were hurt last week.
