STANFORD, Calif. (AP) - Carolina Panthers rookie running back Jonathan Stewart returned to practice Friday and was listed as questionable for Sunday's game at Oakland.
Stewart had missed the previous two days of workouts because of a sore left heel. The first-round pick has been splitting carries with starter DeAngelo Williams.
Stewart has rushed for 362 yards and a team-best five touchdowns.
Reserve defensive tackle Darwin Walker did not travel with the team on Friday will not play against the Raiders because of a sore neck stemming from a car accident on Oct. 25.
