Indianapolis, IN (Best E Casino) - Indianapolis Colts defensive end Dwight Freeney was back at practice Friday after sitting the past two days with a hamstring injury.

Freeney is listed as questionable for Sunday's game against Baltimore.

Safety Bob Sanders will again sit because of ankle and knee injuries. The reigning Defensive Player of the Year hasn't played since the second game of the season when he sustained a high ankle sprain against Minnesota. He then underwent an arthroscopic procedure for his knee in late September.

Cornerback Marlin Jackson is also listed as questionable with an ankle problem, but he has practiced each of the past two days.
