Australia's frontline spinner Brad Hogg has missed training for the second day in a row, placing him in doubt for Saturday night's final World Twenty20 group game against the West Indies.

Hogg was suffering from headaches and flu-like symptoms, but a team spokesman said his condition was improving.

Captain George Bailey said he was hopeful Hogg and Mitchell Starc, who missed an earlier session with gastro but bowled at training in Colombo today, would be fit for the West Indies game.

"They're alright," Bailey said. "Training is quiet without Hoggy, [but] he's pretty good and from all reports Starcy was certainly on the mend. We'll make a call.

"We're certainly not the only team that has had to deal with [illness] in the last few days. That's something we'll have to adjust to."

Players from South Africa and New Zealand have suffered from stomach bugs through the first phase of the event.

Xavier Doherty, who has re-joined the squad after flying home for the birth of his first child, is on standby for Hogg, while Clint McKay and Ben Hilfenhaus are the extra fast bowlers in the squad.

"We'll pass that bridge when we come to it," Bailey said when asked about a possible replacement for Hogg.
