Padraig Harrington has withdrawn from the British Open at St Andrews after his father Patrick passed away last night.
The Dubliner's place in the field will be taken by Sweden's Henrik Stensen - the fourth reserve.
Patrick Harrington, who was 72, was a member of the defeated Cork teams in the All-Ireland Football Finals of 1956 and 1957.
A former garda, Patrick Harrington had been diagnosed with cancer of the oesophagus in March, the week after his son captured his first US Tour title.
Harrington did not play in last week's Scottish Open and rather than travel to St Andrews early had stayed in Dublin because his father's condition had worsened.
At Sawgrass in March Harrington praised the part his father played in his development.
"I have had the best possible background for playing golf, for playing all sports. I could not have got more encouragement from my dad without ever in any sense pushing or wanting to live his life through my sports.
"It was top-notch. When I was growing up my dad was a very competitive, very intelligent player and he just taught me the art of scoring. He would never tell me how to swing the club, but encouraged me to score well and at the end of the day that's really where my talents lie."
Harrington had been drawn to play at 1.20pm on Thursday with Nick Price and Chris DiMarco.
Padraig Harrington, an Irish golfer currently ranked ninth in the Official World Golf Rankings, has pulled out of the British Open at St Andrews to be with his family.
