Charles N'Zogbia's Newcastle United future is in doubt after he refused to sit on the substitute's bench at Watford on Sunday.
The 20-year-old was unhappy with caretaker-manager Nigel Pearson's decision to axe him from the starting eleven and may now be heading out of St James' Park.
"Charles was on the bench originally, but I changed it. He did not really want to be there (on the bench)," said Pearson.
"I have no idea whether he stayed at the ground to watch the game.
"You can make your own judgements about it, but it is very important that everyone associated with the club acts in a professional manner.
"Will there be disciplinary action taken? That is something for this week."
N'Zogbia has made 95 appearances for the Magpies and scored six goals.
