The Facts: Ellington's bad luck with injuries didn't change on Sunday. He suffered a right knee injury in the fourth quarter and didn't return. he severity of the injury is unknown. Coach Bruce Arians said it appears the injury is the posterior cruciate ligament, but that's not certain. Ellington was seen walking without a limp after the game, and Carson Palmer seemed optimistic that Ellington would return. "It's hopefully a day-to-day thing with Andre," Palmer said. "I thought it was a lot more serious with the way he down. But it looks like he's going to be O.K., hopefully."

Diehards Line: If Ellington is out this week, Chris Johnson likely will be the starter. He gained 37 yards on 10 carries in the victory over the Saints. Rookie David Johnson and Stepfan Taylor would be the backups, and Kerwynn Williams could be promoted from the practice squad. “I thought Chris looked good,” Arians said. “He’ll get more touches and we will feel very confident if he is our lead dog.”
