LAKE FOREST, Ill. - The Chicago Bears opened a three-week practice window for rookie receiver Kevin White to determine if they will activate him this season.

White, the No. 7 pick in this year's draft, has spent the season on the physically unable to perform list because of a stress fracture in his left shin. The Bears have until the end of this 21-day period, which began Tuesday, to place the West Virginia standout on the active roster or season-ending injured reserve.

The Bears saw him as a potential starter with Alshon Jeffery. But White started experiencing pain in his shin in June during organized team activities. He had surgery in August after therapy failed to cure his discomfort.
