The Patriots did some shuffling on the back end of their offensive line prior to the team's first practice at training camp, releasing one offensive lineman and signing another.
The team dropped rookie center Matt Stankiewitch and picked up veteran offensive guard Tyronne Green.
Stankiewitch, who was undrafted out of Penn State, had been a long shot to make the team's 53-man roster.
Green spent time with the Patriots before, signing as a free agent this offseason May 13 before being released May 31. The four-year player started 13 games last season at left guard for the Chargers. He's 6-2, 305 pounds.
