According to the Boston Herald, the Patriots thought Gronkowski would benefit more from working with the team's staff in Foxboro:
Gronkowski has been restricted to individual and positional drills, so the Pats believed there was a greater benefit to keeping him home to rehab the knee with full attention from the strength staff rather than bringing him to Richmond to remain limited in practice.
The Patriots are practicing with the Redskins this week ahead of their preseason opener on Thursday.
Gronkowski had knee surgery in January after tearing his ACL and MCL. Injuries to his arm, back and knee have limited him to just 18 games over the last two seasons.
In 2011, Gronkowski set records for most receiving yards (1,327) and touchdowns (17) by a tight end in a season.
