FORMER England U21 international goalkeeper Jason was born in Bishop Auckland and raised in nearby Newton Aycliffe.
Jason joined Boro at the age of 13 from Newton Aycliffe Sports Club. For his school team he played centre midfield, while his classmate Matthew Atkinson, who also went on to Boro's books, kept goal.

In May 2007 he was a key member of the England U17 team that reached the final of the European Championships in Belgium before being beaten 1-0 by Spain.
He was called into the U19 squad in September 2007 just a month after he celebrated his 17th birthday.
His progress was rewarded when he was named in Boro's first team squad for a pre-season tour of Austria in 2007, although a bout of tendonitis meant he missed the trip.
Jason maintained his progress through the 2008-09 season and that summer played an integral part for England U19s as they progressed to the finals of the UEFA European U19 Championships in Ukraine in July 2009 by topping a play-off group.
He was captain for England's final two qualifying games and was named Goalkeeper of the Tournament as England finished runners-up to the hosts.
Together with Josh Walker, Jason was a member of the England U20 squad which contested the U20 World Cup in Egypt.
After an impressive spell on loan to Northampton Town during the 2009-10 season, when he conceded just 10 goals in 13 games, Jason returned and produced a Man of the Match performance in his Boro debut, a 2-1 Carling Cup win at Chesterfield on August 10 2010.
His form earned him an extended run in the Boro first team, which continued after the appointment of Tony Mowbray as manager.
He was also called up for the England U21 squad, although he was he was sent-off just 13 minutes into his debut as a half-time substitute in Germany after he was adjudged to have brought down Boris Vukcevic inside the penalty area.
Jason was rewarded with a new Boro contract in December 2010 taking him to summer 2015.
He was part of England's UEFA U21 European Championships squad in summer 2011 but didn't make an appearance as England exited the tournament at the group stage.
He was also a member of Team GB's historic London 2012 Olympic squad.
His form during the 2012/13 season was rewarded when he was presented with the Ramsdens Player of the Year and Young Player of the Year awards.
A red card in Aitor Karanka’s first game, at Leeds United, and then an ankle injury, meant he lost his place in the team but fit again, he returned for the final game of the 2013/14 campaign as Boro won 4-1 at Yeovil.
