Morris, drafted in the sixth round out of Florida Atlantic, is expected to split carries with Tim Hightower and Tristan Davis. The Redskins are without running backs Evan Royster (knee) and Roy Helu Jr. (Achilles’ tendons). Royster tweaked his knee during practice on Tuesday and said on Thursday that he could play, but imagined that the team was holding him out as a precaution.

Morris last week rushed for 34 yards on 10 carries against the Chicago Bears. He opened the game with a 21-yard carry. The week before, he rushed for 54 yards on 15 carries off the bench.

The Redskins have yet to determine their starting running back. Hightower — working his way back from a torn ACL last season — is scheduled to make his return to the field for the first time today.

The Redskins also will be without starting fullback Darrel Young (hamstring), right tackle Jammal Brown (hip, PUP list) and left guard Kory Lichtensteiger (knee). Maurice Hurt will start at left guard as he has all preseason, Tyler Polumbus will continue to start at right tackle, and tight end Chris Cooley will fill in at fullback.

Leonard Hankerson will start over Santana Moss at the wide receiver position opposite Pierre Garcon.

On defense, Tanard Jackson will start in place of Brandon Meriweather (knee), and Rob Jackson will start at outside linebacker in place of Brian Orakpo (shoulder).
