FOXBORO, Mass. — Brandon LaFell’s 21-day window to come off the PUP list began Wednesday.

The New England Patriots wide receiver returned to practice after beginning the season on PUP with a foot injury. LaFell must be activated to the 53-man roster before playing in a game.

Center Bryan Stork, who’s on short-term injured reserve with head and neck injuries, also practiced. He can return in Week 9.

Defensive ends Jabaal Sheard and Rufus Johnson, guard Shaq Mason and offensive tackle Marcus Cannon were absent for the practice session. Sheard injured his ankle Week 6 against the Indianapolis Colts, and Cannon suffered a toe ailment. Both injuries reportedly are “considered minor.”

Special teams captain Matthew Slater participated in practice, which is a slight surprise. The veteran suffered a leg injury Sunday night against the Colts and was spotted being carted to the X-ray room after the game.
