Magee suffered a shoulder injury during Friday's preseason opener against the Dolphins, Nicki Jhabvala of The Washington Post reports.
Magee is set to be held out of practice for a week, but the issue does not appear to be cause for long-term concern. With the linebacker set to miss Saturday's preseason contest with the Lions, Kain Medrano or Krys Barnes could see a large share of defensive reps.
