Fifth-round rookie Johnny White would serve as C.J. Spiller's backup Sunday if Fred Jackson (calf) can't go. After Jackson went down last week, Spiller got the next three rush attempts. White cleaned up for the final two in garbage time and racked up four targets in the passing game. It's been obvious all year that the Bills have no confidence in Spiller as an inside runner, meaning there's a good chance White gets a fistful of touches against the Jets.
