Australia's coach Darren Lehmann's immediate future is under a cloud after he was diagnosed with a deep vein thrombosis during the final ODI against India.
Lehmann was hospitalised after the condition which he had previously suffered in 2007 was confirmed. Michael Di Venuto, the assistant coach, will take charge of the team during the T20I series against India while Lehmann undergoes treatment.
John Orchard, Cricket Australia's chief medical officer, said Lehmann had noticed calf swelling this morning and reported that to support staff. Later in the day, time was found for him to visit a radiology clinic on site at the SCG, which confirmed the re-emergence of the condition some nine years after he last faced it.
"We had a little bit of a scare in the Australian camp in the bowling innings in that our coach Darren Lehmann has been diagnosed with a deep vein thrombosis," Orchard said. "He had some calf swelling this morning ... then an hour or two later mentioned it to the physio and to me.
"Short-term symptoms and weren't particularly bothering him, but possibly because he's had the issue before he's aware you do report that sort of thing. He's not in any major discomfort or pain, but something he knew to report. One of the factors associated with it is 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.
"[How long] will depend on how long he takes to get stabilised and treated so they're happy to release him. He'll be unable to fly for a week and then we'll assess 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 all ok from a health perspective."
Orchard said it was a possibility that Lehmann's convalescence would cut into the schedule for the forthcoming tour of New Zealand. "The treatment for DVT is to thin the blood, sometimes you can do that really quickly and sometimes it takes a little bit of time because it requires a change of medication," he said. "So it's hard to give an exact time frame but he'll work on that.
"Symptomatically he's fine, he could coach, but we're not going to have him flying around as we move from city to city. It's not definite either way, [New Zealand being affected] is a possibility but we've given a prognosis for this week that he'll miss the T20 series and then it depends on how quickly he stabilises."
Di Venuto has worked with the national team since 2013 following a long and distinguished playing career. Should Lehmann be unavailable for a longer period, Cricket Australia has already flagged a high opinion of the Western Australia coach Justin Langer, who was set to substitute for the head coach during a limited overs tour of the West Indies in mid-year.
Lehmann's wife Andrea was informed soon after the diagnosis was made and Australia's players were briefed on their coach's health after the completion of the match.
"Our first thoughts and concerns are obviously with Darren and his family - health is more important than any cricket match," the CA team performance chief Pat Howard said. "Everyone at Cricket Australia wishes him a speedy recovery.
"We plan for all eventualities and on that basis Michael Di Venuto, who has previously coached Australia A in 2014, will step up to fill Darren's role as Head Coach for the Twenty20 International Series. "We will assess the situation on the basis of medical advice and with Darren's best interests in mind over the coming days."
