Patriots signed former USC and Toronto Argonauts DT Armond Armstead to a reserve/future contract.
Armstead worked out for several teams over the last week or so, including the Colts and Eagles. Armstead was forced to the CFL in 2012 after missing the 2011 season at USC after suffering a heart attack. Armstead, listed at 6-foot-5 and 298 pounds, recorded six sacks last season as the Argonauts won the Grey Cup. ESPN's Adam Schefter called him "the equivalent of a high draft pick."
