A former Celtic youth academy player, McInroy gained significant experience in senior football during his time in Scotland. He made his senior debut while on loan at hometown side Dunfermline Athletic during the 2020/21 season, where he featured in twenty-two matches.

His strong performances led to further loan spells at Airdrieonians and Ayr United, where he scored six goals in twenty-six appearances. This earned McInroy a move to Kilmarnock, where he debuted in the Premier Sports Cup before spending the 2023/24 season on loan at Partick Thistle in the Scottish Championship.

On January 23rd 2025 Kerr joined Shels on an initial one-year deal. The talented Scot impressed so much from the very start that he was rewarded with a multi-year deal in April of the same year.

Industrious and creative, Kerr has imposed his will upon multiple opponents, both domestically and in the European campaign of 2025. He contributed five assists and four goals, including a last-minute winner away to Bohemians to seal European qualification. Hisimmense contribution to Shelbourne’s season was recognised in October where Kerr was awarded SSE Airtricty/Soccer Writers Ireland Player of the Month award. He will certainly be hoping to add more accolades in the coming season.
