The list of Eagles unable to practice Wednesday grew when LOT Tra Thomas (knee) was unable to work.

Initially Andy Reid said only FS Brian Dawkins (neck stinger) and TE L.J. Smith (groin) would be held out of work.

While Dawkins is making progress, according to Reid, the coach indicated Smith suffered a setback.

"Right now he's sore," Reid said. "We've got to let that thing calm down and see how he does here in the next couple of days."

Smith has played in just three games for the Eagles (2-3), who entertain the Chicago Bears (2-4) this Sunday. The reigning division champs both are last in their divisions.

"We look forward to the challenge of playing the Chicago Bears," Reid said. "They are reigning NFC champs. They bring into town an offense that is much improved over the last couple of weeks and a defense that has unbelievable quickness. Obviously their special teams is right now probably the most explosive in the NFL."

The Bears were shredded fopr 311 rushing yards last week in a 34-31 loss to the Minnesota Vikings at Soldier Field.

The Eagles are 5-point favorites.
