Williams (ankle) is questionable for Sunday's game against the Cowboys, Wes Hodkiewicz of the Packers' official site reports.
Williams opened the regular season on injured reserve due to a high-ankle sprain and had his 21-day practice window open during Week 5 prep. He's drawn the questionable tag for Week 6 after string together three limited practices, but he would not be eligible to play unless activated from IR on Saturday.
