Walker carried eight times for 88 yards and a touchdown in Sunday's 39-32 loss to the Saints.
Walker made his mark Sunday with a 69-yard scoring jaunt in the fourth quarter, and with fellow back Rashaad Penny having suffered what head coach Pete Carroll described as a "serious" ankle injury, accordingGregg Bell of The Tacoma News Tribune, the rookie second-round pick looks set to see an expanded role in Seattle's offense, beginning with the Seahawks' Week 6 game against the Cardinals. Look for more context regarding Penny's injury to surface no later than Monday, but Walker could be on track for a multi-game run as Seattle's clear-cut lead back. The Seahawks also have DeeJay Dallas on hand and Travis Homer (ribs) perhaps on track to return from injured reserve later this month, but both profile more as change-of-pace backs than true challengers to Walker for the top spot on the depth chart.
