Doubt over weekend's London matches
The Premier League and Football League will make a decision about weekend matches in London on Thursday in the wake of the trouble in the capital.
The leagues say they have no reason to believe any games outside of London will be affected.
A statement from the leagues said: "The Premier League and Football League are saddened by the recent incidents of civil unrest and the effect it is having on local communities. We are in ongoing discussions with our London-based clubs, the Metropolitan Police and statutory authorities in regard to the staging of the coming weekend's fixtures in the capital."
The statement continued: "The Metropolitan Police has conveyed to us the dynamic nature of the current situation and with that in mind all parties will review the situation on Thursday and make a further public statement at that time.
"With the information currently available to us there is no reason to think any matches outside of London will be affected.
"We are conscious of the need to keep fans informed of any developments and will, of course, keep them as up-to-date as possible through club, league and media channels."
Wednesday night's England v Holland friendly at Wembley was called off on Tuesday morning, as were a number of Carling Cup matches in London and Tuesday night's friendly between Ghana and Nigeria at Watford's Vicarage Road.
