The 29-year-old racked up over 150 appearances across spells in England and Scotland, starring for the likes of AFC Wimbledon, Bradford City, Northampton Town, Morecambe and St Mirren before returning to the League of Ireland in 2023, where he worked with Glens chief Devine.
After seeing off competition from a range of clubs to seal Connolly’s signature, Devine has full faith that the former Republic of Ireland youth international has the required quality to impress in East Belfast.
“Dylan is a player that I know well after working together at Bohemians and I know that he was being sought by clubs both north and south of the border,” he told the club’s website. “With his work ethic he is sure to be a big hit with the fans and as a bonus his huge experience will be of great benefit to our younger players.”
