Australian cricket coach Darren Lehmann has been hospitalised indefinitely after being diagnosed with deep vein thrombosis during the one day international against India in Sydney.
Lehmann's condition isn't thought to be serious, but Cricket Australia chief medical officer John Orchard said Lehmann would miss the upcoming Twenty20 series as doctors treat the clots.
"It's a condition that's got a very good outcome if you get it early, which we have," Orchard said.
"It's all good news, but one of the factors associated with it is that it's unwise to fly until you've stabilised the condition. So he will be absent from the Australian team camp for a short period."
Lehmann, who previously battled DVT as a player in 2008, complained of calf swelling on Saturday morning and was then taken to a radiology clinic at the SCG during Australia's bowling innings.
"Possibly because he's had the issue before, he's a little bit more aware than the average person that you need to report that kind of thing," Orchard said.
"He's not in any major discomfort or pain, but thought something `I should report because I've had a similar condition in the past'.
"It was a lot worse last time he had it, it was post-surgery last time."
Orchard said the 45-year-old would be in hospital for at least the next 24 hours and wouldn't take any part in the Twenty20 series, which begins in Adelaide on Tuesday.
His status for Australia's three-Test series against New Zealand in February is also up in the air.
"The treatment for DVT is to thin the blood. Sometimes you can do that really quickly and stabilise people really quickly, and sometimes it takes a little bit of time because it requires change of medication," Orchard said.
Michael Di Venuto will act as interim coach.
