Crystal Palace defender Tyrick Mitchell has extended his contract with the Premier League club until the summer of 2025.
The 21-year-old left-back has made 18 first-team appearances for Palace, including 14 this season.
Mitchell joined the Eagles in 2016 following a restructure at Brentford's academy and won league titles at U18 and U23 level.
He was handed his Premier League debut against Leicester City last July and has since become a regular under Roy Hodgson.
Crystal Palace chairman Steve Parish said: "This shows once again how our academy can attract the very best young talent and develop them into first-team players.
"Tyrick's progress is an immense source of pride for our club and academy."
Speaking with Palace TV, Mitchell added: "I'm delighted. It's a great place to be and an exciting time so I'm delighted to sign a contract.
"I can see, especially with the academy building now and Academy players coming through, it's a great time."
