Hynoski was regarded as one of the best
fullbacks available in the
2011 NFL draft, until he suffered a hamstring injury during the
NFL Scouting Combine. Due to the injury, his draft stock fell and he eventually went undrafted; however, soon after the NFL labor dispute was settled he received offers from several teams, subsequently making his decision to play for the
New York Giants. Hynoski was given the starting fullback position after the Giants cut veteran
Madison Hedgecock due to injury. Hynoski had no rushing statistics in his rookie season of 2011, being used primarily as a lead blocker for running backs
Ahmad Bradshaw and
Brandon Jacobs. Hynoski did catch 12 passes for 83 yards (a 6.9 yard per reception average). On February 5, 2012, Hynoski became a Super Bowl champion in
Super Bowl XLVI, with a 21–17 win over the
New England Patriots. He caught two passes for 19 yards in the game, and recovered a potentially costly
Hakeem Nicks fumble in the third quarter. On December 30, 2012, his 24th birthday, he scored his first and only career touchdown against the
Philadelphia Eagles. On September 5, 2015, the Giants released Hynoski. ==Coaching career==
