Upon his release from Celtic, Jack joined up with Scottish Championship side Partick Thistle and spent a year in their development squad before being released in the summer.
Ricky Waddell describes Jack as a 'technically good passer of the ball, with adding aggression to his game Jack will be an excellent player.'
Jack joined the club in 2019 and has continued his development in the years since under the tutelage of Ricky.
After enduring an injury riddled start to 2023, Jack returned for the 20233/24 campaign after 10 months out with an ACL injury, to re-implement himself as a key member in the heart of the Braves defence.
