The entry list for the Australian Open has Novak Djokovic down on it.
He will play for Serbia in the tournament, which starts in Australia on January 1.
A small percentage of unvaccinated players and staff will be granted medical exemptions. He was not aware that any players had an exemption.
An independent panel of doctors from the fields of immunology, infectious disease and general practice would initially review applications for an exemption.
The Independent Medical Exemption Review Panel will conduct a second review of applications that meet the national guidelines set by the Australian Technical Advisory Group on Immunisation.
I would love to have Novak here. Tennis Australia's chief executive said that if he met those conditions, it would be great.
He doesn't talk to anyone about it. I'm not going to ask Novak that.
If he is here, I will know that he fulfilled one of those conditions.
After returning to Spain from the Mubadala World Tennis Championship in Abu Dhabi, Nadal tested positive for Covid-19.
Four players have returned positive tests after travelling to the event.
Tunisia's Ons Jabeur and Switzerland's Belinda Bencic have both tested positive in recent days, while Britain's US Open champion Emma Raducanu withdrew before the start of the tournament.
"I'm confident that he will be here," said Tiley.
Players that are positive for now will complete a period of time until they are no longer infectious and will be fine. If you want to play in the Australian Open, you need to test positive now.
