Crawford (ankle) is questionable to return to Sunday's game against the Chargers, Josh Weinfuss of ESPN.com reports.
Crawford appeared to suffer the injury on a punt play in the second half. He was carted off the sidelines to the locker room, where he is undergoing further tests to determine the severity of the injury. Crawford logged three tackles (two solo), prior to his exit, and Wydett Williams will be the lone backup safety if Crawford doesn't return.
