CHICAGO - Former Chicago Bears receiver Johnny Knox has told the Chicago Sun-Times he's giving up football. The Bears terminated Knox's contract Tuesday after he missed this past season recovering from a back injury. Knox needed surgery to stabilize a vertebra after he sustained a back injury against Seattle late in the 2011 season. He had 133 receptions for 2,214 yards from 2009 to 2011 and was on special teams with 55 kickoff returns for 1,506 yards.
