Tonight's friendly between Ghana and Nigeria has been called off following a third consecutive night of violence in London.
Hertfordshire Constabulary announced that they would be unable to police the event, scheduled to take place at Watford's Vicarage Road, as they send a contingent to aid the Metropolitan Police Force this evening.
"The planned friendly between Nigeria and Ghana at Watford FC tonight (August 9) has been cancelled as a precaution due to potential demands on Hertfordshire Constabulary as a result of what is happening in London," the statement read.
"The decision was not taken lightly and was done in full consultation with the club. We hope those fans who had been due to attend the game will understand the reasons why. Any fans who had been planning to travel are being asked not to come to Watford.
"In relation to tickets, please visit the Watford FC website where details will be announced in due course."
