Jack Stafford joined the Academy set-up after a successful trial in February 2022.
Stafford, 21, has penned an 18-month deal after a recent spell with Irish side Waterford FC.
The defender came through the academy at Exeter City before joining Waterford back in February 2021, going on to make 28 appearances for the club.
Jack signed a contract extension in May 2023, extending his time at the club until December 2023.
The centre-back missed almost the entirety of the 2022-23 season due to injury, and will return to fitness for the forthcoming 2023-24 campaign.
