Born in Cork, O’Connor began his professional career in England with Blackburn Rovers after joining their academy as a teenager. Since then, he has built a career spanning England and Scotland, making over half a thousand professional appearances across spells in the EFL and Scottish Premiership.

The versatile defender has enjoyed success along the way, helping Burton Albion secure promotion to the Championship and Aberdeen to consecutive second-place finishes in Scotland.

Capable of playing at centre-back, right-back or even in midfield, O’Connor brings considerable experience across the English and Scottish professional game, as well as having represented the Republic of Ireland at underage level on many occasions.
