Bristol City confirmed Callum O'Dowda was among five players to be released from the club following the expiration of their contracts at the end of June.
The senior midfielder, who was at Ashton Gate for six years, joined youngsters Louis Britton, Barney Soady, Nathaniel Williams and Khari Allen in the fellow City players who won't have their deals extended.
It will be the catalyst of a summer of change at the club with manager Nigel Pearson preparing to build a squad capable of challenging in the top half of the table and beyond.
