Walker (ankle) was listed as a full participant at Tuesday's practice, Bob Condotta of The Seattle Times reports.
After sitting out the Week 14 loss to the Panthers, Walker was listed as a limited participant on Monday's estimated practice report. Seattle returned to the field Tuesday for a more traditional practice session, with Walker taking every rep in the session. The full practice likely puts Walker in position to reclaim his lead role out of the Seattle backfield Thursday against the 49ers, provided he avoids any setbacks during Wednesday's session. Travis Homer, who served as Seattle's primary back against Carolina, will likely move into more of a change-of-pace role Thursday in Walker's expected return.
