James Collins and Richard Dunne have been disciplined after being involved in a row with coaching staff during an Aston Villa bonding session.
Villa manager Gerard Houllier confirmed the club have "reacted strongly" to the behaviour of Dunne and his central defensive partner Collins at a health spa in Leicestershire last week.
The pair have had to explain their actions at club disciplinary panels during the past 48 hours although Houllier was not directly involved.
Villa are also not confirming the exact nature of the punishment handed out to Dunne and Collins.
Houllier said: "There was no fracas, but Dunne and Collins have been disciplined and this is all I can say on the matter.
"The club has reacted strongly and quickly, and now we move on to what is most important for us, the game against Wolverhampton at the weekend.
