Midfielder Michael Essien is in hot waters with the Ghana Football Association for staying away from the warm-up before the final Group G match against Portugal in Brasilia.
It is unclear why the AC Milan player decided to boycott the pre-requisite, which was supervised by assistant coach Maxwell Konadu.
But the widely held view is that, he was protesting against the sacking of his pals Sulley Muntari and Kevin-Prince Boateng for violent behaviour and indiscipline hours before the match.
The Ghana Football Association has vowed to wield the disciplinary axe on the former Chelsea player for his indiscretion.
â€œI think that the coach just mentioned to you that he had just referred the case of Michael Essien-he is made his recommendations; management will take a position on that,â€ Nyantakyi said on Wednesday.
â€œWe are not going to condone any case of indiscipline. You can be the best player in the team. If you donâ€™t behave yourself the axe will fall on you.
â€œYou must also bear in mind that indiscipline is infectious. If you donâ€™t amputate it from the team, it will spread and affect the rest of your players.â€
