The defensive tackle took part in individual drills yesterday for the first time since sustaining a concussion in the pre-season game against the Carolina Panthers earlier this month.
Trestman told the team's website: "He did more today. He's out here working. He ran yesterday. He ran a little bit more today and we're going to continually progress him. He'll work out before the game tomorrow, so he'll be working out every day through Monday and we'll see where he is then.
"All indications are he's progressing that way. Monday shows up, I don't know what the doctors are going to say or the trainers are going to say. But indications are that if not Monday by Wednesday.
"He's still getting himself back into shape. He's got four or five more days to do that and we're working with him to try to get him up to speed. His number of reps could change due to his conditioning level a week from Sunday."
Players suffering from concussions must pass a strict set of league-mandated tests before returning to the field.
