Former Kerry footballer and All-Ireland winner Páidí Ó Sé has died.
Mr Ó Sé, who was 57, was found dead at his home in Ventry this morning. It is believed he may have suffered a heart attack.
He was one of Kerry's greatest players and was one of the few footballers to win eight all-Ireland senior championship medals.
He also served as senior football manager with Kerry, Clare and Westmeath.
Mr Ó Sé is survived by his wife, Maire, and three children, Neasa, Siún and Padraig Óg.
President Michael D Higgins paid tribute to the former All-Ireland winning Kerry captain and manager.
President Higgins said: "Páidí Ó Sé had a reputation that went far beyond his great achievements in sport, and far beyond the boundaries of his own beloved county.
“It was a great contribution", he said, "and I send my sympathies to him and his family, and all those related to him."
President Higgins was speaking at a wreath laying ceremony in Galway.
GAA President Liam O'Neill said he learned of the death of Mr Ó Sé during a Central Council meeting earlier today and there was a deep sense of regret and shock in the room.
Speaking RTÉ’s Saturday Sport, Mr O'Neill said Mr Ó Sé was a wonderful footballer and personality and the GAA was proud to count him as one of its own.
He said he was a larger than life figure and a great ambassador for the sport.
Kerry County Chairman Patrick O'Sullivan said everyone in Kerry is heartbroken and Páidí epitomised everything that was good about Kerry football.
Meanwhile, former Kerry footballer Pat Spillane said he was heartbroken to learn of Mr Ó Sé's death.
Mr Spillane said they had a lifelong friendship and he described Paídí as one of the all time greats of gaelic football.
Mr Spillane said Mr Ó Sé was a warrior and one of the greatest defenders of all time, and he epitomised everything that was good about the people of Kerry.
Another former team mate Ger Power said Mr Ó Sé never had any fear of playing football and his dedication to the game sustained him through the years.
Speaking on RTÉ's Saturday Sport, Mr Power said he played it hard and tough but fair and inspired many teams to success.
Minister for Arts, Heritage and the Gaeltacht Jimmy Deenihan said Mr Ó Sé will be "remembered not only as one of the greatest footballers of his time and also as a very successful manager guiding Kerry to two All-Ireland victories.
"His talent, commitment and energy were legendary", he added.
