Boston-born Irishman Killian Coghlan played in Major League Rugby between 2024-2026. He represented the New England Free Jacks for his entire MLR career.

Deemed a domestic player because he was born in the US, 23yo Coghlan was selected for the USA U20 side in 2020, but the COVID-19 pandemic cancelled all fixtures. He joined the Free Jacks from the University of Cork Constitution in the All-Ireland League, where he had been playing between 2019-2023. Coghlan earned 4 MLR appearances from the bench during the Free Jacks’ successful 2024 season, helping them to go back-to-back and lift his first MLR Shield.

On 6th November 2024, the New England Free Jacks announced the return of Killian Coghlan for the 2025 season where he set career highs across the board. He started more games in 2025 than he played in the season before and earned 9 appearances total, racking up an even 200m gained in possession (20x his total from 2024), and 23 of his 29 total MLR tackles. Coghlan helped the Free Jacks to their 3rd successive MLR shield in 2025, Coghlan’s second. On 24th November 2025 the New England Free Jacks announced the return of Killian Coghlan for his 3rd Major League Rugby season in 2026.
