Lennon Miller has put to pen to paper on a one-year contract extension.
The 17-year-old has committed his future at the club until the summer of 2026.
Despite suffering a broken patella in November, the midfielder has made 14 appearances in all competitions in his breakthrough season.
Miller has already made 19 appearances for the club, scoring two goals in the process.
“This contract extension tees Lennon up for that next chapter of his career,” manager Stuart Kettlewell said.
“He’s already ticked off a few important milestones in his young career but for him to know his future is here, gives him good security going forward.
“It’s very easy for players to get 13 starts at young ages in the modern game and to think the next chapter could be something different.
“It’s important he’s in a place to develop and I believe he’s an example to young modern players to not get too eager for the next opportunity. It comes naturally when you do good things.
“It’s a proper feel good factor for the football club as a whole and I look forward to seeing Lennon back on the pitch.”
Lennon suffered a broken patella against Aberdeen at the start of the month, which has ruled him out for a minimum of three months.
“My injury was a disappointment but to get my contract extended has given me a lift,” Lennon Miller added.
“I always wanted to stay at Motherwell and negotiations have been straightforward from my side of things.
“This club has given so many opportunities and to be rewarded with this, is something I’m grateful for.
“Now my focus is on achieving a full recovery and earning my spot back in the team.”
