On-loan Chelsea defender Matt Miazga has been fined by his club Vitesse Arnhem for grabbing his opponent's groin.
The 22-year-old clashed with Heerenveen's Denzel Dumfries on January 20.
The incident went unpunished at the time, but the Eredivisie club have decided to take action.
Vitesse technical director Marc van Hintum said: "First of all, we regret the commotion that has arisen. We have fined Matt directly after the events because they do not fit the behaviour shown within the fair play concept of the club."
