Andy Murray says Novak Djokovic case 'really not good' for sport

Andy Murray expressed concern for Novak Djokovic on Sunday, saying that other players were shocked and that the furore surrounding the world number one's barred entry into Australia was "really not good for tennis".

The Serbian was hoping to win a record 21st Grand Slam at the Australian Open later this month, but instead of training he has been confined to a room in a hotel in Melbourne used to accommodate asylum seekers.

The 34-year-old is challenging the decision to cancel his visa after being stopped on arrival at Melbourne Airport early on Thursday, and a hearing into the case will be held on Monday.

"I think everyone is shocked by it, to be honest," former world number one Murray was quoted as saying by local media in Australia.

"I hope that Novak is okay.

"I know him well, and I've always had a good relationship with him and I hope that he's okay."

"It's really not good for tennis at all, and I don't think it's good for anyone involved."

Djokovic, who has publicly criticised mandatory vaccines, has consistently refused to disclose his inoculation status and said he had been granted a medical exemption to compete in Australia.

Australian Open chief Craig Tiley blamed conflicting and quickly changing directives in a "challenging environment" for the confusion that resulted in Djokovic being refused entry to the country on a medical exemption.

"(I need to) wait and hear exactly what the situation is before commenting on it further, because again I don't think it's fair because some of it is speculation," Murray said.
