Marion Barber expects to play

IRVING, Texas -- Dallas Cowboys starting running back Marion Barber said he expects to play Christmas night at the Arizona Cardinals after missing the previous three games with a calf strain.

Barber was a full participant in Wednesday's practice.

Barber would not discuss how he's been feeling the last few days or what his role might be on Saturday night.

Felix Jones has started in Barber's absence, but he suffered a bruised shin in last week's game versus Washington.

Jones did not practice on Wednesday and he missed Tuesday's walk-through session as well. Jones said his leg is feeling better and wasn't sure if he was going to practice Thursday.

Starting wide receiver Roy Williams was limited in practice with a groin injury and he wouldn't discuss his chances of playing on Saturday night. He would only talk about not playing in last week's game versus the Redskins. He suffered a groin injury in practice early last week that forced him out.

"You're preparing to play for the game on Sunday, I'd rather get hurt on Sunday in the game instead of practicing and you may not get to play," Williams said.

When asked if he's feeling better this week than last Williams said, "I'm feeling pretty good."

Sean Lee and Gerald Sensabaugh were limited in practice while dealing with their recovery from concussion-type symptoms. Sensabaugh said he felt fine and expects to practice Thursday.

Bradie James (knee) and Keith Brooking (foot) did not practice but that is mainly as a precaution.
