Lions' Frank Ragnow: Carries questionable tag

Ragnow (throat) is questionable for Sunday's game against the Vikings.

Ragnow missed the last two games after fracturing his throat in a Week 14 loss to the Packers. Joe Dahl (back) filled in at center for the last two games, but now Dahl is unavailable for the season finale as well. If Ragnow can't play Sunday, Oday Aboushi or Jonah Jackson are candidates to bump over from the guard position.
