TEMPE, Ariz. (AP) Wide receiver Michael Floyd and tight ends Jermaine Gresham and Troy Niklas returned to practice on a limited basis for the Arizona Cardinals on Wednesday but tight end Ifeanyi Momah is out with a knee injury.

Asked how serious Momah's injury was, coach Bruce Arians said, ''we don't know yet.''

The 6-foot-7, 255-pound Momah made the Cardinals' 53-man roster after being released five times by three teams over the past two seasons. On one memorable play in the preseason against Oakland, two would-be tacklers bounced off of him simultaneously from each side in a violent collision and he kept running for a 38-yard gain.
