On 26 February 2009 Supple was linked with a loan move to Grimsby Town, but this was put on hold by Ipswich in order for the club to find a replacement for the departing keeper.
On 31 January 2008, Supple, along with teammate Billy Clarke joined Scottish Premier League club Falkirk on loan.
[3] Supple was signed due to the injury to Falkirk's first choice goalkeeper Tim Krul, where he made four appearances for the Bairns.
Supple was loaned out to League One side Oldham Athletic on 18 March 2009,[4] following Ipswich Town's signing of Polish goalkeeper, Bartosz Białkowski until the end of the season.
[7] Nine days later, Ipswich Town announced that they had agreed to cancel Supple's contract at the request of the player, allowing him to pursue a career outside professional soccer.
[11] Supple has represented the Republic of Ireland at under-21 level, his only cap in a UEFA European Under-21 qualification game at home to Montenegro on 25 March 2008, which ended 1-1.
Supple excelled in his first full season with his home club St Brigid's, acting as vice-captain during their run to the final of the 2010 Dublin Senior Football Championship.
