The Lions are keeping RB Jahvid Best on the reserve/PUP list. It officially ends his 2012 season. Best can't find a doctor willing to clear him after multiple concussions. There's no guarantee he'll ever step on the field again, making Best nothing more than a flier in dynasty and keeper leagues. Meanwhile, RB Joique Bell will continue to handle passing-down work behind lead back Mikel Leshoure.
