Hubbard rushed seven times for 80 yards in Sunday's 21-18 preseason loss to the Colts.
Hubbard put his athleticism on display by ripping off a 59-yard scamper that made up most of his rushing contributions. On the flip side, he was only able to corral one of four passing targets for two yards. Christian McCaffrey figures to dominate the backfield touches -- both on the ground and through the air -- so the competition between Hubbard and Reggie Bonnafon likely will be for insurance and not much else.
