Anthony Ralston has signed a new four-year deal at Celtic.
The right-back - who joined the club youth set-up aged eight - will remain at Parkhead until at least 2027.
Ralston made his debut for Celtic back in 2016 and racked up appearances in loan spells at Queen's Park, Dundee United and St Johnstone.
Since returning to the Celtic first-team squad in 2021, Ralston has become a regular in matchday squads. He has made 90 appearances and scored seven times for the Parkhead top side.
Commenting on the new contract, he said: “I’m absolutely delighted, and it’s a great feeling to sign with your boyhood club on a new contract.
“It never gets old, that feeling of being able to put pen to paper to secure your future where you want to be.
'Essentially, this is where I want to play my football and it’s another proud moment in my career.'
“I just put my head down every day and worked hard since I signed my last contract two years ago and it’s just been a case of going in, getting work done, doing my best for the team and helping to bring success.
“And I feel that, as a team, we’ve managed to do that, and within that players get their rewards, so like I say, I’m absolutely delighted to get it done.”
And Brendan Rodgers added: “I’m absolutely delighted for Anthony. He was a young player who showed a lot of promise when I was first here.
“He came into the team and played some good games, and obviously he really kicked on when Ange came in and had that early spell where he played quite a lot, and you could see him grow from that.
“So, for me and the squad, I’m absolutely delighted. He’s a Celtic guy who’s come through the system here and I just think that when you have guys like that in your squad, you always get that extra wee bit out of them.
“When I spoke to him a little while back, he’s so happy to commit himself to Celtic.
"He loves being here, he loves being a part of the club and he loves being here and ready to contribute, and I’m very happy he’s decided to sign on.”
