Bruce Arians says Patrick Peterson feels better, still limping

TEMPE, Ariz. – The most important name on the Arizona Cardinals' injury report this week was still limping Tuesday.

Cornerback Patrick Peterson hurt his left ankle Sunday night against Cincinnati, but coach Bruce Arians is optimistic that the four-time Pro Bowler will play against San Francisco this weekend.

“Pat, I think’s going to make it,” Arians said Tuesday night on SiriusXM NFL Radio. “He felt better today.

“That’s the big one.”

There’s another “big one” to keep an eye on this week.

Veteran defensive tackle Frostee Rucker also suffered an ankle injury against the Bengals, but his prognosis wasn’t as bright as Peterson’s.

“I doubt he’s going to make this game,” Arians said of Rucker.

If Rucker doesn’t play Sunday in San Francisco, Arizona will short on defensive-line depth. Arians said there’s a chance the Cardinals could also be without defensive tackle Cory Redding, who is nursing a high ankle sprain.

Arians is also hoping that wide receiver Michael Floyd practices this week, which he says "might" happen. He’s recovering from a hamstring pulled against Seattle on Nov. 15.

As for this week’s fate of guard Jonathan Cooper, who missed Sunday night’s game with a knee injury, Arians said he’s “still not sure.”
