Novak Djokovic has withdrawn from his planned Australian Open warm-up tournament as he is "not quite physically ready to compete".
The Serb great, 38, was set to play at next week's Adelaide International as he gears up for his latest bid for a standalone record 25th Grand Slam singles title.
Djokovic has won 10 of his 24 majors at the Australian Open but lost in the semi-finals on his past two appearances.
He has scaled down his playing time in recent years to attempt to be fresh for the Grand Slams.
"I was really excited about returning as it truly felt like playing at home," Djokovic wrote on Instagram.
