Arizona Cardinals coach Ken Whisenhunt had some good news for fans of the quarterback competition, letting reporters know after Tuesday's practice at Missouri Western State University that he expects Kevin Kolb to be able to play on Friday.

"I think he'll be fine, today he was a little stiff," Whisenhunt said. "It's only two days from the game, so I think as we progress he'll probably do something tomorrow and I expect him to play Friday night."

Kolb left Sunday's game with a rib injury and had been questionable for their next game until now.

Whisenhunt also said that while he's not sure if he will play Friday or not, rookie running back Ryan Williams has shown significant signs of improvement.

"He played well today. I was very impressed with Ryan. His knee was bothering him a little bit but he pushed through it today," Whisenhunt said. "That's what you have to do when you're going back from one of these injuries. I saw Ryan grown up as a pro a little bit today and that was encouraging."

With Skelton getting the start in Friday's game, look for Kolb to come off the bench and try to make a better impression than his 1-for-4 night with four yards and an interception on Sunday.
