FOXBORO — The Patriots held their last walkthrough prior to the opening of preseason games when they conducted a practice in shorts and shells that lasted around two hours on Wednesday. The Pats will kick off their preseason schedule Thursday night when they host Blaine Gabbert and the Jaguars at 7:30 p.m.

Here are a few notes from the walkthrough:

– Among the players not in helmets or practicing were Brandon Tate, Ras-I Dowling, Shane Vereen, Kevin Faulk, James Sanders, Marcus Cannon, Dan Connolly, Chris Morris, Matt Light, Albert Haynseworth, Shaun Ellis, Ron Brace and Mike Wright.

Wide receiver Chad Ochocinco was present, though he wasn’t on the field much, if at all. He stayed on the bench with teammates. Second-year tight end Rob Gronkowksi did not practice Tuesday, but was on the field for Wednesday’s walkthrough.

– Once again, first-round pick Nate Solder saw a healthy amount of action at left tackle with the first unit. With Light out, the rookie faces far less stiff competition in trying to protect Tom Brady‘s blindside in the early going of the preseason, though Sebastian Vollmer, who was lined up at right tackle, has enough experience playing both positions that he could see a fair amount of time on the left side.

– All sorts of special teams plays were practiced, with tight end Will Yeatman doing a good job of falling on an onside kick. Among other things, the safety kick was also practiced.

– While Brady, Brian Hoyer and Ryan Mallett all got their snaps under center, it was teenager Harry Kraft, son of Jonathan Kraft and grandson of Robert Kraft, who stole the show at the quarterback position. Wearing a light blue T-shirt, shorts and a Dean Ween haircut, the youngster (who ESPN’s Chris Mortensen noted attended Peyton Manning‘s camp) worked out of the shotgun and hit Wes Welker with a bullet (relatively speaking) in the end zone. Another pass was just out of Deion Branch‘s reach, though he sold play action flawlessly.

The young Kraft seemed to mean business out there, but unfortunately for him, so, too, did some players. Defensive back Kyle Arrington tipped a pass intended for Vince Wilfork (yes, Vince Wilfork), making Harry Kraft probably the youngest person to experience their “welcome to the NFL” moment. He later went back under center and Malcolm Williams did the unthinkable by actually picking off one of the kid’s passes.
