Dallas (ankle/quadriceps) was a non-participant at Wednesday's practice, John Boyle of the Seahawks' official site reports.
Dallas has kicked off preparations for Saturday's wild-card game in San Francisco with two straight absences, but there's an expectation that he'll be able to suit up this weekend, per Gregg Bell of The Tacoma News Tribune. A return to the practice field Thursday would be a step in the right direction for Dallas, but Thursday's injury report will reveal as much. If he's active Saturday, he'll serve as the direct backup to Kenneth Walker (ankle) with Travis Homer (ankle) on injured reserve.
