McNichols gained 36 yards on 10 carries and failed to haul in his lone target in Thursday's preseason finale against Washington.
Believed to be on the roster bubble, McNichols didn't do much to help his own cause, mustering a long run of only seven yards. The good news for the fifth-round rookie is that Peyton Barber and Russell Hansbrough also had quiet nights. The Bucs may try to sneak McNichols onto the practice squad.
