Middlesbrough will look closer to home for a new central defender.
Boro were forced to pull out of an £8.5 million move for Neven Subotic after a medical highlighted a serious chest problem.
But Jackson, 22, and Morris, 20, for all their talent and promise, lack experience..
The Borussia Dortmund centre-back seemed a vital part of Aitor Karanka’s defensive jigsaw.
But now Hull City defender Harry Maguire appears to be their new target.
Sky Sports report that Boro have made a £4million bid for the 23-year-old, who is keen to leave the KC Stadium despite the Tigers having won promotion back to the top flight.
Speculation is rife that the Teessiders are hoping to conclude a quick deal for Maguire, who only has one year left on his City contract.
But Steve Bruce’s shock departure from the East Yorkshire outfit yesterday may slow things down.
Karanka is keen to act given the defensive problems at the Riverside. Daniel Ayala is out with an ankle injury while Bernardo Espinosa has barely figured this year.
Adam Jackson, who spent the majority of last season on loan at Hartlepool United, where he earned rave reviews, has featured heavily thus far in pre-season.
So too has Hartlepool-born Boro product, Bryn Morris, who has captained England at various youth levels.
But Jackson, 22, and Morris, 20, for all their talent and promise, lack experience.
Maguire finished last season strongly, playing a key part in Hull’s promotion, though he is hardly oozing Premier League nous himself.
Neither is Hungary Under-21 ace Kenneth Otigba, who has been playing for Heerenveen in the Netherlands
