Since going undrafted as a junior entrant in 2011, Siliga had been cut by the San Francisco 49ers, the Denver Broncos, traded to the Seattle Seahawks and cut thrice more. The 6’2”, 325-pounder had been a member of two practice squads and played in one career game. Although after just five weeks on New England’s eight-man roster, Siliga was promoted to the 53-man roster. He’s played in five games since, starting four of them. He’s totaled 23 tackles and three sacks over that span.
