'Injuries are nothing new for the 30-year-old Argentine, who has been sidelined by wrist injuries that have required numerous surgeries throughout his career.'
World number five Juan Martin del Potro will miss next month's Australian Open as he continues to recover from a kneecap fracture he suffered during a fall at the Shanghai Masters in October, he said on Monday.
"Recovery is going great and I will tell you later where I will be making my comeback," he said on Twitter.
"Unfortunately it won't happen in Australia, I’ll miss you @AustralianOpen, but I'm happy with my progress."
Injuries are nothing new for the 30-year-old Argentine, who has been sidelined by wrist injuries that have required numerous surgeries throughout his career.
The hard-hitting del Potro was healthy for most of 2018 and had a career resurgence, winning the title at Indian Wells in March before reaching the US Open final in September.
