Brighton manager Graham Potter has announced that defender Mac Allister will be staying with the club until 2027.
The deal means that Allister will remain with the Seagulls for another four years, and he will continue to play a key role in their defense.
Allister's extension is a huge boost for the team, as he has been one of their most consistent performers this season. He has made 16 appearances so far this campaign, contributing to three clean sheets and two assists.
Potter praised Allister's commitment to the club, saying: "I'm delighted to announce that Mac Allister has extended his contract with us until 2027.
"He's been an integral part of our backline all season and I know he'll continue to play a vital role for us going forward."
Allister himself expressed his delight at being able to stay at the club for such a long time, saying: "It's a great feeling to have my future secured here at Brighton.
"I've had a fantastic few seasons at the club and I can't wait to see what the next chapter brings."
