Orton sat out a 21-14 loss to Tennessee last week with a sprained right ankle. He was taken from the field on a cart late in the first half of a win over Detroit on Nov. 2.

Orton is enjoying a breakout season with 1,777 yards and 10 touchdowns after beating former starter Rex Grossman in a preseason competition.

If Orton can't go against the Packers, Grossman will likely make his second straight start.
