ALLEN PARK — Calvin Johnson, Tony Scheffler, Louis Delmas, Drayton Florence, Corey Williams and Travis Lewis did not practice today (Wednesday).

 However, CB Bill Bentley returned from a two-week layoff due to a concussion and CB Chris Houston was back after practicing on a limited basis last week, but not playing on Sunday.

Mikel Leshoure was back after a two-game suspension and oddly enough was the last player to run onto the practice field. Due to a 48-hour roster exemption, a player does not have to be cut to make room on the roster until 4 p.m. today.

 Also at practice were CB Jerome Murphy who was claimed off waivers on Tuesday and CB Conroy Black who was signed to the practice squad on Tuesday in place of Stephfon Green.

 The Lions will play at the Tennessee Titans at 1 p.m. on Sunday. Ron Pitts and Mike Martz will call the game to be televised on FOX.
