Williams, who caught two passes for 78 yards and a touchdown in Friday's preseason opener vs. the Eagles, ended up exiting the game early due to a hamstring injury, ESPNChicago.com reports. Williams suffered the injury while hauling in a 73-yard touchdown pass from Jimmy Clausen, marking the Bears' biggest play of the night. Considered the favorite to replace the departed Devin Hester in the return game, Williams has been better than anticipated as a receiver, putting him on sturdy ground to claim a roster spot if the hamstring injury doesn't prove too severe.
