LAKE FOREST, Ill. (CBS) — Second-year defensive back Deiondre’ Hall was back on the practice field with the Bears at Halas Hall on Wednesday for the first time this regular season.

The Bears have now opened a 21-day window in which Hall can be designated from a return from injured reserve. He suffered a hamstring injury late in the preseason.

A recent change to NFL rules allows teams to designate two players from injured reserve. The previous rule allowed just one return.

Receiver Kevin White is considered another potential candidate to return this season. Coach John Fox hasn’t ruled out White for the remainder of the season after he suffered a fractured scapula in the season opener.
