IRVING -- The Cowboys returned to the practice fields at Valley Ranch on Monday morning, and cornerback Mike Jenkins (hamstring) was a participant at the walkthrough practice.

Jenkins has missed the last four games with a hamstring injury, and it appears he'll play Sunday at Arizona.

However, wide receiver Miles Austin (hamstring) did not work with the team during the walkthrough and was doing rehab work as he still recovers from his injury.

Austin has missed the last three games because of the hamstring injury.

There was some good news as fullback Tony Fiammetta made an appearance on the practice fields wearing a sweatsuit and a knit cap. Fiammetta hasn't played the last two games because of an undisclosed illness.

Fiammetta was in the Cowboys weight room riding a stationary bike, which is a good sign as he was getting sick when he was working out. Monday's events could lead to a return in the coming weeks.

Update: After Monday's walkthrough, Fiammetta declined to speak with reporters as he left the locker room.

"I don't have anything to say," Fiammetta said as he walked to the players parking lot.

Also missing the session were Gerald Sensabaugh (foot), Jon Kitna (back) and Josh Brent (knee).

Felix Jones (ankle), Kyle Kosier (foot) and Mat McBriar (leg) all participated during the walkthrough session held with no helmets.
