According to Day, his mother Dening has lung cancer, which was initially thought to be terminal, and is scheduled to undergo an operation tomorrow. Day lost his dad to stomach cancer at the age of 12.

“It’s really hard to even comprehend being out there on the golf course,” said Day, who added that his form has been affected by the events. “It’s been very, very emotional as you can tell. I went through this with my dad, so I know how it feels, and it’s very hard to see my mum go through it as well.”

Day received an overwhelming amount of support from his peers, including Tony Finau, who had been in Austin all week as first reserve only to see the 2015 PGA champion bow out after six holes.

To clear up any dispute. Absolutely no hard feelings to Jason Day. My thoughts and prayers to him and his family at this time. #cancersucks

Further support came from the likes of Luke Donald and also Darren Clarke, who lost his first wife Heather to cancer in 2006.

Best wishes to you and your mum @JDayGolf fingers crossed mate #FUCancer

Tough to watch @JDayGolf in his press conference. Thoughts are with his mum, him and his family as she fights the battle.

Praying for @JDayGolf and his family. He's always been one of my role model. He handles himself with such class on and off the course.
