Three Boro youngsters have been called up to represent England at their respective age levels.
Dael Fry, Marcus Tavernier and Stephen Walker will represent the Young Lions in the upcoming international window.
Fry is included in Aidy Boothroyd's England Under-21 squad, who will play friendlies against Poland and Germany as they resume preparations for this summer’s U21 EURO Finals.
Tavernier will once again link up with England's Under-20s, who have matches at home against Poland and away to Portugal in their latest Euro Elite League fixtures.
Walker, currently on loan at MK Dons, completes the line-up with his selection in the England Under-19 squad. Keith Downing's side host the Elite Qualifying Round at St George's Park, with games against Czech Republic, Greece and Denmark to decide which one nation will progress to this summer’s U19 EURO Finals in Armenia.
The trio join first team players Darren Randolph (Republic of Ireland), Mo Besic (Bosnia and Herzegovina), Paddy McNair and George Saville (both Northern Ireland) in receiving international call-ups, as well as fellow youngster Enes Mahmutovic (Luxembourg), with Paddy Reading selected for Scotland's Under-21s for the first time.
