Jason Day will be sitting out the Australian Open, the World Cup of Golf, and a charity event in the Philippines due to ongoing rehabilitation for a back injury he suffered last season.
The World No. 1 announced his absence on Twitter Thursday in a statement that cited warnings from his physicians.
"I regret that I will be unable to come home to Australia this year," Day said. "My best wishes to all in Sydney at the Open and to Adam [Scott] and Team Australia in Melbourne at the World Cup. I appreciate the understanding and patience of my Australian fans."
Day's back injury was a frequent issue during the last stretch of the 2016 season. While his prognosis for a healthy return is good, doctors advised him against the long hours of travel to Australia, urging him to focus on resting and recharging for the 2017 season.
The absence also affects a charity match Day was scheduled to play against Rory McIlroy in Manila, Philippines. Day had hoped to bring his mother back to her native country, where the Day family lost relatives in Typhoon Haiyan.
