Ross Tierney has departed the club joining Irish side Bohemian F.C. for an undisclosed fee.
The 23-year-old made 38 appearances, scoring four goals since joining the club in 2021.
Scoring against both Rangers and Celtic, and netting a last minute equaliser against St Mirren, Tierney was part of the side that clinched European football in the 2021/22 season.
Tierney went out on loan last season to League Two side Walsall and made 35 appearances down in England.
He now joins his former team Bohemian for a second spell.
The club thanks Ross for his service and wishes him all the very best in the future.
