Seattle's backfield has been absolutely decimated and will hand Peterson a workload despite being on the Seahawks' roster for less than a week. The three active running backs from Week 12 are all currently questionable: Alex Collins (core), Rashaad Penny (hamstring), and Travis Homer (calf).
Fantasy Impact:
Depending on the availability of each member of this backfield, the Seahawks will take a committee approach. For a struggling offensive unit facing a top defense in the San Francisco 49ers, it's a situation to avoid.
