2GB broadcaster Alan Jones has remained positive about his prostate cancer surgery this Saturday - and will remain on-air until Wednesday.
The 67-year-old is scheduled to have an operation to remove the cancer at Sydney's St Vincent's Hospital on Saturday.
He will spend Thursday and Friday resting.
A spokeswoman for Jones said the breakfast host was in good spirits.
"He's feeling fine, he's very positive," the spokeswoman said.
Jones, who has vowed not to give up on his radio career, is expected to be off air for two to three weeks while he recuperates.
"He'll probably be off for a few weeks but it's up in the air because it's one of those things you don't know how you're going to feel after a major operation," the spokeswoman said.
He will be replaced by Jason Morrison.
"It will be business as usual on the show, and Alan has been very supportive and encouraging." Morrison said.
Jones shocked fans and Australian media when he made the announcement about his illness out of the blue.
The influential radio host and former Wallabies rugby coach found out about his illness after a biopsy in May, but did not tell friends, family and colleagues until earlier this month because he did not want to cause concern.
Jones had been training the Australian Barbarians rugby side last week, sandwiching the coaching job inbetween his radio commitments.
While making the announcement about his illness, Jones was stoic about his condition.
"We don't do dying here" he told a packed media conference at 2GB's Pyrmont studios.
