Celtic manager Gordon Strachan has hinted he could impose a nightclub ban on his players after Aiden McGeady was reportedly attacked in Glasgow in midweek.
The Hoops' 22-year-old midfielder has become a magnet for trouble in recent years, partly due to his decision to choose the Republic of Ireland over Scotland.
Strachan said: "We have to look at the guidelines for that to protect the players. I'll review them."
Tuesday`s incident reportedly ended with McGeady sustaining facial injuries and came in the same week controversial goalkeeper Artur Boruc was photographed drinking and smoking cigars when he was home in Poland recuperating from a knee injury.
The former Legia Warsaw keeper, 28, was left out of his country's squad for their opening World Cup qualifiers after breaching disciplinary rules after a friendly match with Ukraine in August.
And last month he was fined £500 and given a severe reprimand over gestures he made to Rangers fans during the last Old Firm derby at Celtic Park.
However, asked about Boruc's conduct, Strachan replied: "It was his weekend off. He can do what he wants.
"Do you spend time with your girlfriend? Do you go to the cinema with her? Would you like her to kiss you now and then? That's what Artur has done.
"I still go to the cinema with my wife. I still kiss her. She doesn't like it, but there you go. It's only human nature.
"He never broke any rules and never broke any guidelines. He's (back) training so I don't have a problem with it."
