FOXBOROUGH -- Although he wasn't participating, Patriots center David Andrews was present as a spectator at practice Tuesday afternoon.

It was reported Monday he has a blood clots in his lungs and his season may be in jeopardy. Of course, it's great to see him out of the hospital and at the facility.

There were several players not spotted including, Benjamin Watson, Derek Rivers, Shilique Calhoun, Lance Kendricks, A.J. Howard, Cameron Meredith (PUP) and Trent Harris.

Rookie running back Damien Harris returned after missing the last two days.

It's worth noting rookie wide out N'Keal Harry was moving much better than he has in the past several weeks. He's only played in one preseason game, which was the first one in Detroit. He suffered a lower body injury after making the second of two catches and really hasn't done much since.

The Patriots will host the Giants in the fourth preseason game Thursday night.
