Kenneth Walker, running back for the Seattle Seahawks, is expected to play in Sunday's Week 14 game against San Francisco. He had missed the past two games due to an oblique injury but practiced in full on Friday. Walker will likely return to his lead-back role, which was filled by Zach Charbonnet in his absence. Charbonnet is also expected to play, but quarterback Geno Smith's availability is uncertain due to a groin injury.
