FOXBORO -- Patriots tight end Rob Gronkowski returned to practice today after missing yesterday's workout for unknown reasons. The Pats will release their first injury report of the week this afternoon, but Gronk hasn't been listed for injury reasons since Week 14, so it's possible he won't be on it.
Right guard Tre' Jackson missed today's workout. Jackson hasn't been absent since Nov. 14 when he missed two weeks of workouts due to a left knee injury. He was present in the locker room before the workout, so it's unclear why he was out.
The Patriots practiced in shells.
