Checking in on Armond Armstead

FOXBOROUGH -- First-year defensive lineman Armond Armstead has opened Patriots training camp on the non-football illness list, but his absence is for a different reason than a past heart condition that led to him going undrafted in 2012 and landing in the Canadian Football League, according to Bill Belichick.

Belichick, as expected, didn’t go into detail when asked if there was any long-term concern with Armstead’s status.

“If we have anything, we’ll talk about it,” he said. “Not at this time.”

Armstead is an intriguing prospect who draftniks have said was on his way to becoming a high-round draft pick while playing at Southern Cal, but he wasn’t medically cleared to play in the 2011 season and went undrafted. He landed in the CFL in 2012, had a strong season, and the Patriots signed him to a three-year contract in January (a pact which includes $655,000 in guaranteed money).

Armstead projects as a possible third interior defensive tackle, behind Vince Wilfork and free-agent signee Tommy Kelly.

In his absence, former practice squad player Marcus Forston has taken those reps as the first interior tackle to rotate into drills after Wilfork and Kelly.
