New England Patriots defensive lineman Armond Armstead underwent surgery to deal with an infection, the team announced.
Armstead is on the non-football illness list.
"Armond Armstead had surgery to treat an infection," the Patriots said in a statement. "Armond is in good condition and is expected to make a full recovery. A timetable has not been set for his return to football.”
Armstead had a heart attack at USC, but Patriots coach Bill Belichick indicated this is unrelated to that episode.
“I think it’s a different situation,” Belichick said.
Armstead, 22, was signed this winter following a stint with the Toronto Argonauts in the Canadian Football League.
