Walker (ankle) didn't practice Wednesday, John Boyle of the Seahawks' official site reports.
Walker wasn't listed on Tuesday's estimated injury report, so his absence one day later likely is maintenance-based due to the ankle issue that he's dealt with since early December. Whether he's able to rid himself of a designation ahead of Saturday's wild-card game at San Francisco won't be confirmed one way or another until after Seattle releases its final injury report of the week Thursday. Since getting hurt Week 13 at the Rams, Walker sat out Week 14 but has proceeded to real off 98 touches for 450 yards from scrimmage and no touchdowns while suiting up for the last four contests.
