World number five Juan Martin del Potro has announced his withdrawal from this month's Australian Open as he continues to recover from a kneecap fracture he suffered during a fall at the Shanghai Masters in October.
“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 Indian Wells title in March before reaching the U.S. Open final in September.
