Blackburn's pre-season friendly with Dutch club NEC Nijmegen has been cancelled due to the threat of fan violence.
The decision to cancel Sunday's game was taken by the police and the local authorities in Nijmegen following disturbances involving Rovers supporters in Deventer on Friday and Saturday.
Nijmegen are set to host a fans' open day just hours before the scheduled game, with the local authorities expecting around 8,000 visitors including families with young children.
A statement on the Gelderland-Zuid section of the www.politie.nl website read: "The deputy mayor of Nijmegen has decided to cancel the exhibition game between NEC and Blackburn Rovers.
"That match was due to be played today at 2.30pm during the annual open day of NEC.
"Supporters of the English club Blackburn Rovers were involved in rioting in Deventer on Friday and on Saturday there was a confrontation with supporters of NEC Nijmegen in the city.
"On the basis of serious signals to the police that a confrontation would take place again today, deputy mayor Henk Beerten in consultation with police, judiciary and mayor Hubert Bruls decided to cancel the match this afternoon.
"Today, some 8,000 visitors are expected at the open day of NEC which starts at 12.30pm, including many families with children.
"With the serious threat of unrest in the Goffertpark around the exhibition game, it is not sensible to play this game today."
A statement on Blackburn's official website read: "Both clubs wish to express their disappointment that such a decision has been necessary."
NEC said in a statement that they regretted the decision to cancel the match, but understood it was taken with regard to safety.
