(ALLEN PARK, MI) – The Detroit Lions waived defensive tackle Daylon Mack. The team announced the move Friday. The NFL's transaction report listed the move with a failed physical designation. The Lions acquired Mack off waivers from Baltimore last weekend. Mack was a fifth-round draft pick by the Ravens last year out of Texas A&M. Mack dealt with knee and hip problems last year and eventually went on injured reserve.
