Asked whether he'd ruled out Moss for Sunday's game, Redskins coach Joe Gibbs said: "Yeah. Looks more and more like it will be hard to have him go."
On Washington's official injury report, Moss was downgraded
Friday from questionable to doubtful.
Moss has more yards receiving (435) than the other four wideouts on the roster combined (397). He was injured during Washington's last game, a 36-22 loss at Indianapolis on Oct. 22, and hasn't practiced since.
"You're going to miss Santana. We all know that. We have to have other guys step up," Gibbs said. "It's why we have the guys we do at that position. Hopefully that will happen."
Moss was wearing sweats without pads Friday.
"Looking at me now will tell you what's going on. I feel pretty good, but at the same time, you see how I'm dressed," Moss said. "How can you go out there and do something when you haven't been out here putting in the work? ... No reason to be sugarcoating nothing. It's evident what's going on."
"That has us concerned," Gibbs said.
Lloyd, who missed time with thigh and shoulder injuries, practiced Friday.
Right tackle Jon Jansen, meanwhile, rested as a precautionary measure, Gibbs said.
Washington, coming off its bye week, enters on a three-game losing streak and with a 2-5 record. The NFC East rival Cowboys are 4-3.
