The Redskins could be without Santana Moss for Sunday's game against the Dallas Cowboys.

Moss missed practice for the third consecutive day as he continues to recover from a hamstring injury and was downgraded to doubtful on the injury report.

Moss was not optimistic that he would be available against the Cowboys, although he held out hope that the hamstring injury would improve by pre-game on Sunday. But Redskins coaches do not typically play players who have missed practice time.

"How can you go out there and do something when you haven't even put out the work?" Moss said on Friday. "It's not right for me to say I'm going to jump out there and try and go 100 miles per hour.

"Feeling good walking or feeling good jogging is nowhere near how it's going to be doing something that's football-related, especially with what I do: running, stopping and cutting."

If Moss cannot play, then the Redskins would likely start Brandon Lloyd and Antwaan Randle El at wide receiver.

Randle El has 18 catches for 167 yards and one touchdown this season, while Lloyd has 11 catches for 164 yards.

Complicating matters is the health status of David Patten, who has also missed practice time this week and is listed as probable with a hamstring injury.

It appears Patten will be a game time decision.

Said head coach Joe Gibbs: "That has us concerned. We'll work him out before the game and we'll have to make a decision."

Wide receiver James Thrash could also see action as the Redskins' third receiver.

The Redskins have a pair of wide receivers on the practice squad in rookie Mike Espy and second-year player Steven Harris. Asked if the team would sign a practice squad receiver before the game, Gibbs replied: "I wouldn't think so."
