Armstead went undrafted in the 2012 NFL draft and later signed with the Toronto Argonauts of the CFL. He led the Argonauts in sacks this past season and was named a CFL all-star. Armstead was released by Toronto on Friday, reportedly to pursue NFL opportunities.
Listed by the CFL at 6-foot-5, 298 pounds, Armstead reportedly drew interest from the Patriots prior to last April's draft, and could be on their radar for a spot on their offseason roster. NFL rules prohibit teams from signing players from CFL rosters within the same season, so Armstead cannot join the Patriots for the playoffs.
