Eagles guard Todd Herremans sat out practice Tuesday with what the Eagles are calling a sore left foot.
Herremans missed five games last year after undergoing surgery for a stress fracture in the foot. He had been golfing over the weekend and anticipated getting back into the swing of things Tuesday.
During the Tuesday Organized Team Activity held indoors, Eagles CB-FS Marlin Jackson injured his right ankle on the FieldTurf, according to the Eagles.
That was the preliminary evaluation pending X-rays.
Jackson was in considerable pain and had to be helped off the field.
