Washington Redskins coach Mike Shanahan said wide receiver Anthony Armstrong likely will return to full action this week and could play in the preseason game at Chicago next Saturday.

Armstrong injured the AC joint in his right shoulder during a collision and hard fall to the turf during the Redskins’ Aug. 3 practice.

He spent the last week limited to individual drills and wore a yellow ‘non-contact’ jersey to ensure that he wouldn’t sustain contact and suffer a setback.

“We don’t want to have him bouncing around, because it’s still a second-degree separation in that AC joint,” Shanahan said. “But it shouldn’t keep him from playing.

Armstrong fielded punts on Saturday and said he is eager to return to action. He said that if it had been the regular season, he would have resumed full activity much sooner.

“It feels the best it’s felt in this whole week-and-change,” Armstrong said. “I’m going to be ready to go, but [Shanahan] has the full trigger. … If it was Week 1 New Orleans, yeah, I’m playing, but since we’ve got a little extra time, we wanted to take that extra time and let it heal back all the way. But, I’m ready to go whenever they say.”
