The Detroit Lions are expected to fire Offensive Coordinator Mike Martz after Sunday's season finale against Green Bay. The Lions will replace the veteran coach with Receivers'Coach Kippy Brown. The little blotch on Martz's resume shouldn't be enough, however, to keep him unemployed for long, The Times said. Martz will likely be pursued by the struggling San Francisco 49ers as a replacement for current Offensive Coordinator Jim Hostler. The 49ers are apparently turning to Martz because of his familiarity with the NFC West and successful pedigree as coach of the St. Louis Rams (2000-2005), the paper reported.
