As expected linebacker Justin Durant and tight end Tony Scheffler are out for Sunday’s game against the San Francisco 49ers. Both have concussions.

This will be the third straight game that Durant misses. He was leading the team in tackles when he went down in Minnesota.

Scheffler was injured on Monday night and couldn’t finish the game.

Neither one was cleared to practice all week.

Also out will be safety Vincent Fuller who injured his elbow on Monday night in his first game with the Lions.

That leaves Detroit thin at safety. Amari Spievey (hamstring) is questionable but expected to play. Louis Delmas and John Wendling are the only other healthy safeties.

CB Aaron Berry (groin), WR Rashied Davis (foot) and T Jason Fox (foot) are also listed as questionable.

For San Francisco, cornerback Tramaine Brock (hand), wide receiver Braylon Edwards (knee) and running back Moran Norris (fibula) are out.
