Former Australian Rugby World Cup winner and Saracens fly half Michael Lynagh is stable but still being treated in a Brisbane hospital after suffering a stroke.
The 48-year-old, regarded as one of rugby's all-time greats, was rushed to hospital complaining of headaches and blurred vision.
"Former Queensland Reds and Wallabies captain Michael Lynagh was hospitalised in Brisbane on Monday night after suffering a stroke," Queensland Rugby Union (QRU) said in a statement.
"Mr Lynagh remains in a stabilised condition in the Royal Brisbane Hospital and is undergoing tests in an effort to discover the cause of the illness."
Lynagh moved to London when he played two seasons for Saracens and is now a regular rugby pundit for Sky Sports and during the Rugby World Cup he worked for ITV also in the UK.
He was part of Australia's Grand Slam winning team in 1984 and was a key player in the Wallabies' 1991 World Cup win. He won won 72 caps for Australia in the 1980s and 1990s as well as having a distinguished state career for Queensland
Lynagh captained Australia from 1993 to 1995 and held the world points scoring record when he retired with 911 points. He also held the world record for most conversions (140) and is still Australia's leading point scorer.
He went on to play for Saracens in England and has had a successful career as a marketing director since his retirement from rugby.
Australian Rugby Union chief executive John O'Neill said his office had been inundated by enquiries from Australia and around the world requesting information on Lynagh's condition.
"It is an indication of the status he holds within our great game," he said.
"Michael has been a wonderful Wallaby, but also a wonderful man, which explains the outpourings of support and good luck messages to him."
Another former Australia captain, Andrew Slack, who wrote Lynagh's authorised biography, said he was shocked at his illness.
"There's not a lot known but he's stayed very fit since retiring some years ago," he told ABC radio.
"I think this is a bolt out of the blue, there's no doubt about that."
