GOLF: Jason Day's persistent back problem has forced him out of next month's Australian Open and World Cup of Golf.
The world No.1 has struggled with the injury for the latter part of the US PGA Tour and had to pull out of the BMW Championship and season-ending Tour Championship.
He was set to play in the Australian Open at Royal Sydney from November 17-20 before defending his World Cup of Golf title with Adam Scott at Kingston Heath in Melbourne the week after.
Now his physician has ordered him to rest up.
"I regret that I will be unable to come home to Australia this year,” Day said in a statement.
"I was looking forward to playing in the Australian Open and teaming up with Adam Scott on one of my favourite courses, Kingston Heath.
"My plan is to return home to Australia in 2017.
"My best wishes to all in Sydney at the Open and to Adam and Team Australia in Melbourne at the World Cup. I appreciate the understanding and patience of my Australian fans.”
Day, 28, will also have to sit out a charity event against Rory McIlroy in the Philippines.
The pair were due to play in the Battle For A Cause in Manila.
"I'm quite saddened about missing our trip to the Philippines,” Day said.
"I was planning on taking my mum back to her home in the Philippines to visit where we lost members of our family in the typhoon.
"We are to raise much-needed funds for these worthy causes brought on by this disaster and I look forward to being there in 2017 to help get this work done.”
