Former England captain Tony Greig, who was last month diagnosed with lung cancer, is to undergo surgery on Tuesday.
The 66-year-old spoke to the Channel Nine commentary team, of which he is usually a member, during their coverage of the first Test between Australia and South Africa in Brisbane.
Greig was candid about the situation, saying: "It's not good. The truth is I've got lung cancer. Now it's a case of what they can do. I'm going in on Monday for a Tuesday operation. Then we'll start to fight back after that."
He added: "Once they've done the operation the plan is to have some chemotherapy to see if we can make a dent in this setback I've had.
"It's been an incredible, very short journey so far. You've got no idea how much one misses going to the cricket on a day like today. It takes a little bit of getting used to."
