Limerick have announced the departure of midfielders Tobias Kainz and Tommy Walsh with immediate effect.
The duo were signed by former manager Martin Russell but have been deemed surplus to requirements by new boss Neil McDonald and allowed to pursue opportunities with other clubs.
Austrian midfielder Kainz signed in March after spending a period on trial with the club in pre-season.
He previously had spells with SC Heerenveen in the Netherlands and Sturm Graz in Austria. More recently, he was with Austria second-tier side Wiener Neustadt and regional league club SV Grodig.
20-year-old Scot, Walsh signed in March after spending five years with Rangers, during which he became the club's youngest-ever player when he made his league debut in 2012 aged 16.
He spent time on loan with Stenhousemuir, Dumbarton and St Mirren in Scotland's lower leagues before being released by Rangers in January of this year.
The pair made their competitive debuts for the Blues in a 3-0 EA Sports Cup defeat at home to Cork City.
Walsh made a sole league appearance as an injury time substitute in a 1-1 draw with Shamrock Rovers in Tallaght in April, while Kainz was limited to the bench in the same game.
