Veteran defensive tackle Grady Jackson, who signed as an unrestricted free agent, hasn't practiced in the offseason because he's still recovering from knee surgery in February.

Jackson still could miss the first four regular-season games because his suspension from last year -- a violation of the steroid policy -- is pending. Source: MLive.com
