Van Vossen hit with three game ban
Van Vossen was found guilty of kicking NAC Breda defender Jurgen Colin in an off-the-ball incident in their recent Eredivisie tussle.
The KNVB arbitrary commission meted out a three-game ban for van Vossen although the decision angered De Graf coach Peter Bosz.
"This is just ridiculous," stormed Bosz. "There is a question of will. This weekend, I have seen more fouls that should have resulted in red cards."
Bosz also took a sideswipe at his opposite number, NAC coach Henk Ten Cate, for bringing the van Vossen incident to the KNVB's attention.
He added: "I cannot shirk the impression that Ten Cate has made the KNVB observer alert."
