Coach Jim Zorn had been optimistic all week that Moss would play, but the receiver's third consecutive day of inactivity on Friday tempered expectations. Moss is questionable on the injury report.
Moss was injured in last week's win over Detroit, a game in which he caught a 50-yard touchdown pass and returned a punt 80 yards for a score. His 658 yards receiving rank fifth in the NFL.
Moss will get an extra day to heal because of the Monday night game. With rookie Malcolm Kelly already out with a knee injury, the Redskins will have only three healthy receivers if Moss can't play.
