The centre-half duo are understood to have been fined two weeks' wages in the wake of their actions during a team bonding session at a health spa in Leicestershire last week.
Yet Houllier is adamant the two-day exercise was an overall success and that Villa are in the right frame of mind as they prepare for the vital home clash with Wolves.
Houllier said: "I don't think team morale has been affected.
"As far as I am concerned, the rest of the team trained well and is ready and prepared for the Wolves game.
"We need to keep that [the incident] to one side and prepare for the Wolves game and the rest of the season. The rest of the team enjoyed the two days and it was a good exercise in terms of commitment, energy, enjoyment."
