Tony Vidmar has withdrawn from Australia's World Cup squad because of medical reasons and admits his career may be at risk.
The former Middlesbrough, Cardiff and Rangers player, now with Dutch side NAC Breda, made the decision after medical tests revealed an irregular heartbeat.
The 35-year-old 75-cap veteran told www.footballaustralia.com.au: 'It's something that has come as a real shock but due to the seriousness of the situation I had no other choice in the interests of my own health and the team that I withdraw from being considered for the World Cup squad.
'When I return to Australia I'll have some further examinations and once I have that information I'll decide if I will play on but in the short term it would be too much of a risk.
'Of course I would love to play in the World Cup, it's been a dream of mine and I have been in four campaigns but until I am fully aware of my health situation I can't risk playing.
'Though I won't be on the field with my team-mates I'll be joining the rest of Australia in giving them my full support.'
