Barry Ferguson and Allan McGregor have been dropped for Scotland's World Cup qualifier tonight after a breach of discipline, the Scottish Football Association confirmed.
It is understood the Rangers duo were involved in a drinking session at Scotland's Loch Lomond base after they returned from Saturday's 3-0 defeat by Holland in Amsterdam.
An SFA spokesman said: 'We can confirm that there has been a breach of team discipline.
'This has been dealt with within the squad. The focus of today is victory this evening and we will be going all out for three points.'
Burley's dramatic action casts doubt over the future of Ferguson who, despite winning 45 caps, has played just once for Scotland in the last 14 months.
McGregor, who will be replaced by regular number one Craig Gordon, has only won four caps.
Burley's own future almost certainly depends on tonight's result against Iceland.
A draw or defeat would all but end Scotland's hopes of reaching their first major finals since the 1998 World Cup finals in France.
The former Hearts and Ipswich boss will radically alter the side which lost to Holland on Saturday night.
Celtic skipper Stephen McManus looks to have recovered from an ankle injury and will come in for Christophe Berra. McManus is likely to take the armband from Ferguson.
Tottenham defender Alan Hutton will come in for Graham Alexander who is out with a hamstring injury.
