"Eight Lions starters, 10 players total, did not participate in practice Wednesday.
The sitting starters were quarterback Matthew Stafford (shoulder), kicker Jason Hanson (knee), wide receiver Calvin Johnson, tight end Tony Scheffler, running back Jahvid Best (toes), defensive linemen Corey Williams and Cliff Avril (quadriceps) and linebacker DeAndre Levy.
Johnson, Best, Scheffler, Williams and Levy were presumably given maintenance days."
