Pharrell Willis has capped off a milestone week in his fledgling career by signing a new professional contract at Boro.
The 19-year-old made his senior Boro debut with a bright cameo appearance from the substitutes' bench in Tuesday's 3-0 win over Blackpool.
Having first penned pro terms over the summer, this new agreement runs until 2025.
Born in London, Pharrell joined the club's Academy as a 16-year-old after impressing at Independent FC.
