Injured Washington Redskins wide receiver Josh Morgan expressed encouragement over how his strained left hamstring has progressed, but said that he doesn’t want to return to the field prematurely.

Morgan, signed as a free agent from San Francisco in the spring, suffered the injury during Monday's practice, and hasn’t practiced since. He is competing for the starting receiver position opposite Pierre Garçon, but this week can only watch while Leonard Hankerson gets the bulk of the reps at that position.

Morgan said the hamstring injury is new to him, so he doesn’t know exactly how long it would take for him to fully recover, but Coach Mike Shanahan said that the receiver, who tested his leg out with some work on the treadmill, could return as soon as Monday.

Morgan missed the final 11 games of last season with a broken bone in his lower right leg.

He was limited during spring practices with Washington, but had resumed a full workload by the start of training camp.

Although disappointed, Morgan said that he doesn’t feel pressure as a result of lost time on the field.

“You know you’ve got to be healthy” he said. “You know you have to be healthy. You won't be your best if you're not healthy, and you can't really compete. So there's no point in me being out there before I'm ready. I'm feeling good, and I'm just going to listen to the trainers, and be patient, and do what they tell me and come back when they say I can.”

Morgan is one of three injured wide receivers. On Wednesday, backup Lance Lewis pulled a groin, and is expected to be sidelined about two weeks. And on Thursday, Anthony Armstrong injured his right shoulder during a collision. Shanahan said X-rays would be ordered to ensure that Armstrong's collarbone is intact.
