Williams is questionable to return to Sunday's game against the Dolphins due to a ribs injury, Bob Condotta of The Seattle Times reports.
Williams entered Week 3 with a knee issue but was ultimately cleared to play. He's now dealing with a separate issue. Williams has been a pass-rushing monster for new coach Mike Macdonald in Seattle. While Williams is out, Jarran Reed, Byron Murphy, Johnathan Hankins and Mike Morris will have to pick up the slack.
