Gaelic football The
St Loman's clubman represented
University College Dublin in the
Sigerson Cup and Westmeath at all levels and starred as Westmeath reached the
Leinster Under-21 Football Championship final. He also played in two games of the 2011
All-Ireland Senior Football Championship and went on to become a permanent fixture in the Westmeath team. Heslin scored 1–9 in the
2015 Leinster Senior Football Championship semi-final victory over Meath, his team winning the game despite having to make up 11 points and not having beaten Meath for a long time. In the
2022 Tailteann Cup final he overtook
Dessie Dolan as Westmeath's all-time championship top scorer. He retired from inter-county football in January 2025.
Australian football Heslin represented the
Ireland national Australian rules football team, that won the
2011 Australian Football International Cup and kicked four goals in the tournament.
Richmond Football Club Heslin joined the
Tigers as a rookie in the
2012 Pre-season Draft. After only three months on the Tigers' rookie list, homesickness proved too much for the St Loman's clubman, and he resumed his inter-county career with Westmeath. == Career statistics ==
