Fulham's Zat Knight was fined and left out of this weekend's 3-2 defeat against Manchester United after breaking a midweek curfew. Knight, 25, reportedly broke the rules with a visit to a nightclub and boss Chris Coleman was clearly still unhappy with the defender despite his apology.
Coleman said: "Zat Knight was left out of the squad for a disciplinary reason.
"I haven't really made my mind up about the next game at Charlton yet, I've got two weeks to think about that."
Knight had played in Fulham's defeat by Tottenham last Monday at White Hart Lane.
But the defender did not even make the bench against United, with Alain Goma replacing him in central defence.
"There are rules and regulations that the players know they have to stick by," Coleman added.
"Zat overstepped the mark and he was punished. He's said sorry and I respect that, but I'm still far from happy with him."
