The Irish forward arrived at Brunton Park on a three-and-a-half-year deal for an undisclosed fee in January 2024.

Kelly started his career with hometown club Derry City, before moving to University College Dublin AFC. He then moved on to Dundalk in 2018, where he scored seven goals in seven league appearances with the County Louth club.

From there, he made the switch to St. Patrick’s in July 2020 – and this time he scored three goals in two league appearances.

It was with Bohemians where Kelly really found his feet having signed in January 2021. He scored 21 goals in 31 appearances for the Bohs and ended the season as the league’s top goalscorer.

In January 2022, he signed for Rotherham United and scored on his debut to secure the Millers’ promotion to the Championship in a 2-0 victory over Gillingham. He scored six goals in his 51 appearances at the New York Stadium.
