Soon after, Williams relieved Keith Van Horne against Tampa in September, then was inactive for the final 12 games of the 1993 season.
In addition to his starting duties, Williams blocked or deflected eight field goal attempts through 2001.
Williams was the last active player on the Bears that remained from Mike Ditka's tenure as head coach.
Williams was a team ambassador throughout his career, and was the veteran recipient of the Bears' Brian Piccolo Award following the 2001 season.
