On-loan Juventus striker Fausto Rossi also faces disciplinary action after breaking the club's code of conduct.
Cordoba will carry out an investigation and if necessary will take disciplinary action against Nabil Ghilas, Rossi, Bebé and Khrin, after they broke the code of conduct of the football club on Saturday, reports AS.
All four players were caught out in the early hours of the morning in a cocktail bar with a club training session scheduled for a 1030 start on Sunday morning.
Cordoba captain Abel Gomez remarked: "After losing at home, one should go home. These players have asked for forgiveness and this should go no further. The only thing to add is that we all need to pull together as a group.
"Those players who arrived at the club later or the younger member of the squad may make mistakes and they need to be reminded of just how important this football club is to the fans. They need to be aware of the hardship this club has gone through to reach the top flight and our current situation is damn difficult."
