The Patriots announced 11 roster moves on Monday, including the placement of first-year defensive lineman Armond Armstead on the reserve/non-football injury list.
Armstead had surgery for an infection in July.
New England re-signed two rookies — cornerback Stephon Morris (ex-Penn State) and defensive lineman Scott Vallone (ex-Rutgers) — whom were waived earlier in August.
The club released the following players: wide receiver Kamar Aiken, rookie cornerback Brandon Jones, linebacker Niko Koutouvides, cornerback LeQuan Lewis and rookie long-snapper Mike Zupancic.
Rookie wideout Mark Harrison has been placed on the reserve/NFI list like Armstead, the Patriots said. The club also put rookie defensive tackle Cory Grissom and offensive tackle Marcus Zusevics on injured reserve.
