Kenneth Walker, running back for the Seattle Seahawks, is listed as questionable for Sunday's game against the San Francisco 49ers due to an oblique injury. Walker and Zach Charbonnet both returned to practice as limited participants, with Charbonnet dominating backfield work in the past two weeks. DeeJay Dallas has been the backup, but Charbonnet's knee contusion forced him out in the fourth quarter of last Thursday's loss to Dallas.
