Inappropriate images of the left-back appeared in a Sunday paper during the Baggies' players Christmas party on the weekend but Clarke felt the case was already closed as the club had already sorted things out with the 28-year old.
"As far as we are concerned, it is closed and we moved on. Has Ridgewell been sanctioned? The matter has been dealt with internally. I don't want to talk about it," Clarke said.
"If the players want to organise a night out, then I've got no issues with that.
"You expect the boys to go out and have a good night together, spend a bit of time in each other's company, have a laugh and a joke and behave themselves. They are grown men, they are not children."
