Silvestro is a 6-foot-3, 267-pounder who was with the Patriots last season after going undrafted out of Rutgers.
"I'm just trying to see what I can do to help the team out and do whatever I can do," Silvestro said. "I'm trying to learn as much as I can as fast as I can."
"That was a good experience," Silvestro said. "That was something you don't forget."
Silvestro has registered no NFL statistics in one career game.
