The Redskins continue preparing for Monday night’s game against Pittsburgh with the third of four days of work at Redskin Park. Clinton Portis, Carlos Rogers and LaRon Landry returned to practice after doing nothing (Portis, Landry) or very little (Rogers) on Wednesday and Thursday. Portis was in the limited participation category today. Santana Moss was not practicing because of a hamstring injury. Coach Jim Zorn said Moss will “definitely” be a game-time decision. “Feeling like I felt last week – it’s getting better every day,” Moss said. “You just got to go off how your body feels. My body will let me know how it feels come Monday.” Said Zorn: “Santana is coming right along. He got rid of the soreness and did some drill work. … I don’t want to test it to where it will strain, I want to test it to where it continues to feel good every day. I don’t want him to go out there and play a couple plays and say, ‘It doesn’t feel good.’ If he can play, I want him to participate fully.” Ladell Betts, Jason Taylor and Malcolm Kelly remain out.
