Cincinnati Bengals All-Pro 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. Source: Associated Press SteveRobWhatever's Take: Atkins was originally ruled questionable before being downgraded to out. The team's leader in sacks (5) was seen on the sidelines with his knee wrapped in a big bag of ice. There's no further word on the severity to his injury.
