WASHNGTON — Although wide receiver Santana Moss (hamstring) sat out practice for the third consecutive day, his injury has improved, and he could play Monday night against the Pittsburgh Steelers at FedEx Field, Coach Jim Zorn said Friday.

"Santana's coming right along," Zorn said. "He got rid of his soreness, he did some drill work today, but did not participate in practice. "We'll just continue to progress. I don't want to test it to where it's going to strain. I want to test it to where it continues to feel good every day."

Moss and other injured players should benefit from an extra day off, "but you just don't know" what's going to happen with a hamstring, Moss said. "It's getting better every day. I can't tell you no more than that. That's the truth, though. It's getting better every day."

Zorn said Moss would be a game-time decision. Washington would have to make major adjustments in the passing game if Moss, the team's only consistent deep threat, sits out.

"I don't want him to go out there and just play a couple of plays and then go, `You know, it just doesn't feel very good,' " Zorn said. "I want him to go out and, if he's going to play, participate fully in the game. I'm always optimistic, but I say that and we just have to wait and see. I was optimistic last week as well about a couple of guys that couldn't go. They just flat couldn't go. We just have to wait and see."
