The Lions return to practice today in Allen Park. Head coach Jim Schwartz said Tuesday that cornerback Bill Bentley should be back at practice this week following a concussion. Cornerback Chris Houston and safety Louis Delmas remain questionable for Sunday's game at Tennessee, but Schwartz said both players are getting healthier. Yesterday, the Lions claimed cornerback Jerome Murphy off of waivers from the Saints and released cornerback Kevin Barnes. Detroit also signed un-drafted rookie cornerback Conroy Black to the practice squad and released running back Stephfon Green.
