Armstead, 23, did not play a snap for the Patriots after signing with the team in Feb. 2013. He was placed on the Non-Football Injury List on Aug. 23, 2013, after undergoing surgery for an infection.
Armstead was once a projected first- or second-round pick while at USC, but a heart attack he suffered in 2011 ended his USC playing career, and he signed with the Toronto Argonauts of the Canadian Football League after going undrafted. In 2012, he sued the university, saying the painkillers he was given caused his heart attack.
It has been a pleasure being around Armond, as he gave everything he could to play for us. Armond worked extremely hard since joining us last February. ... While it is unfortunate he will not be able to play football, Armond is an outstanding young man who has a very bright future in whatever path he chooses.
