Kelly, who had been critically ill on a life-support machine, died in Dublin's Beaumont Hospital on Tuesday, after suffering head injuries in a fall at Kilbeggan.

The 25-year-old sustained his injuries when Balmy Native, trained by his boss Dessie Hughes, came down in the Joe Cooney Memorial Handicap Chase.
Champion trainer Martin Pipe, who gave Kelly his first ride in the Martell Grand National on Dark Stranger
in 2001, led the tributes.
Pipe said: "He was a very talented jockey and I had a lot of respect for him. He had his first ride for us in the Grand National two years ago.
"It's a great shock and sadness for everyone.

Kelly gained his first Cheltenham Festival success in March on Hardy Eustace for Hughes in the Royal & SunAlliance Novices' Hurdle.
When his death was announced, the last two races at Gowran Park on Tuesday night were abandoned as a mark of respect.
And racegoers at Beverley, Salisbury, Yarmouth, Hamilton and Sandown will pay tribute with a minute's silence on Wednesday.
Irish racing officials have also announced Thursday's evening meeting at Tramore, the first day of their four-day festival, will be postponed until Monday.
The death was the first jockey fatality from a fall on an Irish racecourse for more than 20 years.
