Williams was a late scratch from Friday's preseason game with a tight hamstring, ESPNChicago.com's Jeff Dickerson reports. Williams returned to practice this week after he missed most of the previous two weeks with the hamstring injury, but the issue apparently resurfaced in untimely fashion. He was once in prime position to claim returning duties for the Bears to open the regular season, but unless Williams returns to full health and proves effective in the team's final exhibition, he could end up being cut.
