Allen was diagnosed with a herniated disc in his back after the end of the 2014 season, Dan Wiederer of the Chicago Tribune reports.

Analysis:

Allen had a rough first season in Chicago, dealing with pneumonia, a rib injury and the back issue on his way to just 5.5 sacks. He should still be a key part of the defense in 2015, but with the Bears signing Pernell McPhee this offseason, Allen is in danger of losing some snaps.
