Ajax’s Eredivisie match against Groningen was abandoned after just nine minutes because fans of the relegated hosts twice launched fireworks onto the pitch.
The players were sent off in the sixth minute as smoke bombs were thrown before a fan rushed onto the pitch with a banner calling on the Groningen board to resign.
Three minutes after the restart, more fireworks were launched.
The referee canceled the match according to the new Dutch rules.
During a Dutch Cup semi-final between Feyenoord and Ajax last month, a lighter thrown from the crowd hit Ajax midfielder Davy Klaassen and severed his head.
The Dutch FA have ruled that all matches will be stopped if a player or official is hit by something from the crowd. He also said games would be temporarily stopped if a projectile is thrown that doesn’t hit anyone, and if that happens a second time, play should be stopped.
It’s the fourth Dutch Eredivisie match this weekend that has been temporarily halted.
Ajax are third in the league, with Feyenoord closing in on the title.
