Coach Brad Childress said Friday that Williams's condition is unrelated to the neck problem that kept him out of the first seven games of the season. Williams was hurt Wednesday when he fell hard on his shoulder during the special teams portion of practice. Williams said it was "one of those freak deals."
If Williams can't play at Tampa Bay, rookie Tyrell Johnson will return to the starting lineup.
Last week, Childress listed defensive end Jared Allen as doubtful with a shoulder injury, but Allen suited up and played well against Green Bay. Allen is listed as questionable this week.
