Young forward Jeremy Sivi has extended his Boro stay with a new contract.
Adding a further year to his terms, the 20-year-old is now committed to the club until summer 2025.
Sivi, who hails from London, originally joined Boro from the Onside Football Academy in 2021.
He scored five goals in 12 appearances for Boro's Under-21s in 2022/23, and was nominated for PL2 Player of the Month in March.
The youngster has been included in Boro's senior squad on a handful of occasions, and made his professional debut as a substitute in the Carabao Cup against Blackpool in August 2021.
