Walker (ankle) doesn't have an injury designation for Thursday's game against San Francisco, John Boyle of the Seahawks' official site reports.
Less than an hour after head coach Pete Carroll said Walker would be listed as questionable, the final injury report shows the running back with no game designation at all. Walker is thus expected to step back in as the lead runner, though it'll be against a top defense and with some possibility that he cedes more snaps to Travis Homer than he typically would. Fellow running back DeeJay Dallas (ankle) is listed as questionable and could also be an option to avoid putting too much of the load on Walker.
