Australia head coach Darren Lehmann has been hospitalised after being diagnosed with deep vein thrombosis.
The 45-year-old's condition was confirmed after Australia's six-wicket defeat to India in their fifth one-day international of the series in Sydney on Saturday.
Lehmann, who has been Australia coach since June 2013, will be absent from the team's Twenty20 series against India, meaning that assistant coach Michael Di Venuto will take charge.
Cricket Australia's chief medical officer Dr John Orchard told cricket.com.au: "It's more a scare than something to worry about, but it will require him to have a bit of an absence because we'll be playing it safe. It's a condition that's got a very good outcome if you get it early, which we have.
"So it's all good news, but one of the factors associated with is it's unwise to fly until you have stabilised the condition. So he will be absent from the Australian team camp for a short period. "And that will depend on how long that will take for him to get stabilised and treated so they're happy to release him.
"He's very sensible about it and wants to put his health first so he's happy to hand over the reins to make sure he's going to be okay from a health perspective, which is what we expect."
Lehmann previously suffered the condition in 2007.
