Sunderland keeper Jordan Pickford has extended his contract at the Stadium of Light until 2020.
The 21-year-old was on loan at Preston North End until December.
He made his Black Cats debut in the FA Cup against Arsenal earlier this month and played in Saturday's Premier League defeat by Tottenham.
"It's always great to see a local lad progress through the academy ranks especially for our fans," manager Sam Allardyce told the club website.
"Jordan is an exceptional talent, who has already demonstrated that he is comfortable playing at the highest level."
