The Broncos could go with a running back by committee with rookie Montee Ball, Ronnie Hillman and Knowshon Moreno, reports the team's official website.
The report cites coach John Fox's history in Carolina of using multiple running backs: Stephen Davis and DeShaun Foster, then Foster and DeAngelo Williams, then Williams and Jonathan Stewart.
The report says Ball has the chance to start, but he will share carries and playing time with Hillman and Moreno.
