Kevin Quinn, from Glanworth, Co Cork, died shortly after the throw-in during a match between Harbour Rovers and Newtownshandrum.
A post mortem carried out on Saturday found he died of natural causes.
Cork County Board chairman Jim Forbes, who will attend today’s Requiem Mass, described the young man’s death as tragic.
Spectators at the game said the teenager was challenging for the ball when he clutched his chest and fell forward. Fianna Fáil councillor Frank O’Flynn described Kevin as “the life and soul of the parish”. His loss was devastating for his parents, Sean and Helena, his younger brother, Seán Óg, his sister, Natasha, and his club, Harbour Rovers. Kevin is also survived by his girlfriend, Ailish.
“His team-mates are shattered, I have never seen so much grief. People are finding it hard to come to terms with this,” said Mr O’Flynn.
Kevin attended school at Coláiste Chraoibhín in Fermoy. He had recently begun an apprenticeship as an electrician. He will be laid to rest in St Dominic’s cemetery, Glanworth, following Requiem Mass at Holy Cross Church, Glanworth.
Kevin is the sixth young person to die while playing sport in Ireland this year.
Andrew Fitzgerald, 10, from Limerick, died earlier this month when a goalpost collapsed on him as he played soccer in Co Limerick.
Last month, Gaelic footballer, Noel Quill, 23, from Wexford, was found dead in his bed the day after a junior football championship match. In March, Tyrone captain Cormac McAnallen, who led his county to their first All-Ireland, died from a heart virus. Armagh teenager John McCall died weeks later from heart failure while representing Ireland in the under-19 World Cup in South Africa and, in June, soccer player Ken Byrne, 25, collapsed and died on the pitch while played in a Kilkenny League Division 2A game.
A month previous, John Byrne, 37, died after playing a game for Kilkenny Rugby Club.
