Six-times champion and Swiss tennis maestro Roger Federer has withdrawn from the Australian Open 2021.
The World No. 5 last featured in January this year in the Australian Open before undergoing knee surgery.
"In the end, Roger ran out of time to get himself ready for the rigours of a Grand Slam and he's very disappointed he won't be coming to Melbourne in 2021," said Australian Open Tournament Director Craig Tiley in an official statement.
"The Australian Open has always held a special place in his heart -- remember it was Roger who first called the AO the 'happy slam'," he added.
The mega-event will take place at Melbourne Park from February 8-21 and will feature singles, doubles, and wheelchair competitions. Defending champ Novak Djokovic and women's singles legend Serena Williams were among the entries named for the Australian Open on December 24.
