Dominic Thiem will decide by the end of December whether to play at the Australian Open after withdrawing from the upcoming ATP Cup and Sydney ATP 250 events due to injury.
The Austrian has not played since suffering a wrist injury at the Mallorca Open in June. He was unable to defend his US Open title this year and also pulled out of the World Tennis Championship exhibition event in Abu Dhabi.
Thiem, 28, said his aim was to play at Melbourne Park in the year's first major, adding his wrist was "almost at 100 per cent".

"After speaking to my team we have decided to return to Austria instead of flying directly to Australia," Thiem wrote on Twitter. "Unfortunately, I caught a cold (and tested negative for COVID-19) while in Dubai and was unable to practise last week.
"I will therefore not be in the physical condition required to be able to play the ATP Cup and Sydney ATP 250. After not competing for the last six months I can't take the risk of coming back too soon and picking up a further injury."
He continued: "Overall, the time I spent in Dubai was great as I have increased the intensity and level of practice. We will make a final decision about my participation by the end of December."
The ATP Cup starts on January 1, while the Sydney ATP 250 tournament begins the following week.
The Australian Open gets underway on January 17 where Novak Djokovic will be defending his men's singles title.
