Peat was involved in the decision to ban Ferguson and McGregor
Scottish Football Association president George Peat will not be present at Thursday's board meeting after undergoing exploratory heart surgery.
The meeting will now be chaired by SFA First Vice President, Campbell Ogilvie.
The SFA is expected to review the recent 'Boozegate' incident involving Barry Ferguson and Allan McGregor.
Peat was instrumental in banning both players from playing for Scotland after they were seen making V-signs to the media during a recent Scotland match.
The Rangers pair were told they would never play for Scotland again after making offensive gestures to the media while sitting on the bench during the recent World Cu qualifier against Iceland at Hampden.
Team manager George Burley is expected to answer questions about the affair when it is raised at Thursday's SFA board meeting.
The drinking session at Cameron House Hotel on the shores of Loch Lomond followed the squad's 0400 BST return from a 3-0 World Cup qualifying defeat in Netherlands.
Food was laid-on for players and staff, while the players were permitted to have a drink.
However, the events that followed led to midfielder Barry Ferguson and goalkeeper McGregor being dropped to the bench for the match four days later against Iceland because of their behaviour.
Rangers also announced that both had been suspended without pay for two weeks and it appears likely that they will leave the Scottish Premier League club in the summer.
Ferguson was also stripped of the Rangers captaincy.
