Jack Watson

Shamrock Rovers signed Jack from Arklow Town where he was a regular scorer with their Leinster Senior League intermediate team and in February 2014 Jack was included in the Hoops' reserve side that competed in the 2014 First Division. He went on to make 15 league appearances in the centre of midfield for Rovers' First Division side, as they surprised some with a sixth place finish in the league. Jack returned to the U19 squad at Shamrock Rovers for a short while after the First Division season finished before moving to UCD in February 2015.

In his first season at UCD Jack made 22 league appearances and scored four goals as the Students finished third in the table and claimed a promotion play-off spot. He played in the first leg against Finn Harps but missed out through injury for the second as Harps went through 3-1 on aggregate. Jack also came off the bench in UCD's Europa League home match against Dudelange. In 2016 Jack scored twice in 13 league appearances but then left UCD at the end of the season to sign for Pat Devlin at Cabinteely.

Jack scored three times in 27 league appearances for Cabinteely in 2017 and remained at the club in 2018.

In December 2020, Jack signed with Athlone Town from Bray.
