Carroll says Ken Walker III dealing with a hernia issue. Says he doesn’t know yet what that means.

The hope is Walker will be ready to go for Week 1 the team said via other reports. But, Walker will miss valuable time in camp going forward. Penny is back to full strength so at this point he looks like the leader in the backfield, at least until Walker is up to speed.

So only now, with Chris Carson out of the picture following plans to retire due to a neck injury, Rashaad Penny is heading toward the start of the season as the Seahawks' clear-cut RB1, coming off a torrid five-game stretch at the end of last season in which he led the NFL with 671 rushing yards.

Seattle re-signed Penny to a one-year deal worth $5.75 million, including $5.07 million guaranteed, the third-most guaranteed money given to a running back this offseason. Penny finished the season on fire, racking up 671 rushing yards and six touchdowns in his final six games. Per ESPN’s Brady Henderson, Penny is “in the driver’s seat” to be the team’s starting back, but Penny has missed 28 of a possible 65 games in his four-year career, so durability just hasn’t been there. He led the league in yards after contact per attempt and was 15th in broken tackles per attempt. He will probably begin the season as the starter, but second-round pick Walker is waiting in the wings.

Seattle will officially release him with a failed physical designation. Under the CBA, that allows Carson to receive several million in injury protection benefits. Seattle does right by him, according to Rapoport. There were rumblings of this as far back as last year, given the nature of the injury. From a fantasy standpoint, this officially clears the way for Penny and Walker to take over a majority of the RB workload.
