With DeAngelo Williams in line to miss time with a knee injury, Toussaint will serve as Le'Veon Bell's top backup Sunday against the Cowboys, the Pittsburgh Post-Gazette reports.
Toussaint's stint as the Steelers' No. 2 back figures be a multi-week deal with Williams facing a 4-to-6 week recovery, though it's also possible that the team brings in some added backfield depth. In any case, with Bell entrenched as the starter, Toussaint is not a fantasy lineup option, though he now represents a useful insurance policy for Bell owners.
