Roda JC striker Krisztian Nemeth has been banned for five matches following his sending-off in Tuesday night's KNVB Beker defeat to AZ Alkmaar.
The 25-year-old Hungary international was disappointed to have not won a penalty as the game approached the hour mark and, after making physical contact with referee Serdar Gozubuyuk, he was shown the red card by the official.
Roda went on to lose the match 2-0 with a Bart Biemans own goal setting AZ on their way after 32 minutes at Parkstad Limburg Stadion ahead of Nemeth's dismissal, before Aron Johannsson's goal two minutes later sealed the win.
Nemeth released a statement on the club's official website stating that he has apologised for his actions.
He told rodajc.nl: "After I was knocked over in the penalty area, and therefore did not get the penalty that should have been given in my opinion, I've let myself go emotionally and I barged against the referee Gozubuyuk with my chest.
"It was a mistake and I apologise.
"This is not like me as a player and I also realise I have let down not only myself but also the team.
"I will accept the punishment that the KNVB has imposed on me."
The suspension means the struggling side, who have won just one of their last nine league games, will be without Nemeth for the all-important Eredivisie matches against Utrecht, PEC Zwolle, Feyenoord, NAC Breda and ADO Den Haag.
Roda technical manager Leon Vlemmings voiced his disappointment over the issue, adding: "Internally we had a chat with Krisztian about the incident. During that he expressed regret.
"We obviously do not condone this behaviour as a club and accept the penalty imposed by the KNVB. For us the matter is now closed."
