The Redskins placed right tackle Jammal Brown on the active/physically unable to perform list on Friday because of soreness in his hip.
Brown is ineligible to practice until he passes a physical.
Brown was praised for his progress in offseason workouts after finishing each of his previous two seasons with the Redskins on injured reserve. He was acquired from the Saints after missing the 2009 season to recover from hip surgery.
Second-year tackle Willie Smith, an undrafted free agent who started the final three games at left tackle, will get most of the reps in Brown's absence.
