If Reggie Bush is unable to go in Week 2, Jarryd Hayne could find himself with a much larger role come Sunday.

Geep Chryst, the 49ers offensive coordinatory, indicated Hayne would remain the backup running back to Carlos Hyde, in the event Bush cannot play.

Hayne saw action in Week 1 backing up Hyde after Bush left the game early due to what was later deemed a calf injury.
