It has been announced that Dr Tim O'Mahony, a former dual star with Cork and Dublin, passed away earlier today.
Dr O'Mahony was the founding chairman of Toyota Ireland, who are one of the current All-Ireland SFC sponsors.
He involved himself in other sports as well, as he was behind the building of the renowned golf course on the Mount Juliet estate in Co Kilkenny, and Toyota are also the sponsors of Heineken Cup winners Munster.
Paying tribute to Dr O'Mahony, GAA President Nickey Brennan said: 'Tim O'Mahony was a man who left an indelible imprint on the sporting, business and cultural landscape of Ireland. His passing will be mourned by all who had the privilege of having known him.'
Brennan also extended his sympathy to the O'Mahony family, and his vast number of friends around the country.
