Dundee United youngster Sam Cleall-Harding has penned a new deal at Tannadice, tying him to the club until 2029.
The defender, 19, has made 10 appearances for the first-team under Jim Goodwin and has recently broken into the starting XI.
Initially making his breakthrough at the end of last season after an injury crisis limited Goodwin's options, he has had to wait for his chance this campaign.
Although he joined Airdrieonians as part of a club cooperation agreement, he has remained in Dundee and been part of every matchday squad.
He didn't make his first appearance until December though, coming off the bench against Hibs. That impressive cameo was rewarded with three starts against Livingston, Hearts and Hibs.
"I'm delighted to commit my future to the club I have supported my entire life - it's a dream come true having the opportunity to represent Dundee United every week," he told club media.
"I'm really grateful for the trust the manager has placed in me - playing in the Scottish Premiership has really helped me develop. I want to repay the faith the club have shown me by becoming a valuable member of the squad."
