Newhouse and the Giants have agreed to two-year, $3.25 million contract, Caplan reports
In four years in the league, the 26-year-old has appeared in at least 15 games each season, but has only started seven games over the last two years. He was drafted in the fifth round, No. 169 overall, by the Green Bay Packers in the 2010 NFL Draft.
He was the starting right tackle for the Packers in 2011 and 2012, but left Green Bay after the 2013 season.
The Giants finished last season 6-10 and in third place in the NFC East. New York was No.13 in points scored, No. 10 in yards gained and No. 19 in point differential.
