FOXBOROUGH — Dion Lewis was spotted zipping through the locker room but not on the practice field Wednesday as the Patriots held their first workout of the week in preparation for Sunday's tilt in Buffalo.

The running back remains on the PUP list after having a recent followup surgery on his knee. Lewis's original surgery came last November after he tore his ACL in a game against the Redskins.

Patriots coach Bill Belichick was asked earlier in the day if his dynamic back would be on the field Wednesday and said simply, "If he is, we'll let you know.''

Once a player on PUP returns to practice, the team has three weeks to activate him to the 53-man roster or he goes back on PUP for the rest of the season.


Guard Tre' Jackson, also on the PUP list, was at practice, but just for stretching. The clock has not started on him, either.

Otherwise, the Patriots had full attendance at the shorts-and-shells session, including linebacker Kyle Van Noy, who was acquired from the Lions Tuesday.

Defensive tackle Anthony Johnson, who had been waived earlier in the week, was back on the field as a member of the practice squad. The team cut guard Chase Farris to make room for Johnson.

The practice squad players of the week included running back Tyler Gaffney, guard Ted Karras, receiver DeAndrew White, safeties Jordan Richards and Brandon King, and defensive tackle Malcom Brown.
