And the youngster is set to continue to his learning curve by joining Rotherham United on a season-long loan.
The England youth international has put pen to paper on a long-term deal with the club and follows in the footsteps of Daniel Ayala, George Friend, Ben Gibson and Adam Forshaw in pledging his future to Boro.
Having missed the opening weekend of the new Premier League season due to injury, Fry, who has only just turned 19, will now continue to learn his trade in the Sky Bet Championship after joining Rotherham United on loan.
Currently away with England U20s, Fry, another product of Boro's Academy, has made seven appearances with Boro's first team. He made his debut in a goalless draw away to Preston North End on the opening day of the 2015/16 season.
