Jason Day is skipping the Australian Open and World Cup of Golf in his home country because of the back injury that forced him to withdraw during the final two PGA Tour events of the season.
Ranked No. 1 in the world, Day said Thursday that he has been advised to rest his back and that the November trip to Australia would have conflicted with his rehabilitation and rest periods.
The Australian Open is Nov. 17-20 at Royal Sydney, and the World Cup is the following week at Kingston Heath in Melbourne.
"I regret that I will be unable to come home to Australian this year," Day said in a statement. "I was looking forward to playing the Australian Open and teaming with Adan Scott on one of my favorite courses, Kingston Heath, the following week at the World Cup."
Day won three PGA Tour titles this year, the Arnold Palmer Invitational, World Golf Championships-Dell Match Play and The Players Championship.
