The Premier League will make a decision on Thursday on whether this weekend's opening round of top-flight matches are to be postponed after trouble spread to Manchester and the West Midlands.
The Football League is also in 'ongoing discussions' with police as it is considered whether this weekend's matches in riot-hit London will go ahead.
The Leagues have released a joint statement and say the 'dynamic nature' of the events has been conveyed by the Metropolitan Police.
England's friendly with Holland at Wembley on Wednesday has already been called off, while Tuesday's Carling Cup matches at Crystal Palace, Charlton, and West Ham were postponed.
Violence also spread to Bristol on Monday night and as a result Bristol City's cup match against Swindon was also called off.
A statement from the leagues read: "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 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.
"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."
Although the statement adds that there is 'no reason to think any matches outside of London will be affected', it was released before violence flared in Manchester and the West Midlands and the Premier League will now decide on which top-flight matches across the country should go ahead.
In the capital, Fulham are due to host Aston Villa in their season-opener on Saturday, Queens Park Rangers are due to welcome Bolton, and Tottenham are scheduled to play Everton at White Hart Lane.
In the Championship, Crystal Palace are set to face Burnley, Nottingham Forest travel to Millwall, and Watford play Derby.
Leyton Orient host Tranmere in League One, while Barnet and Dagenham & Redbridge host Port Vale and AFC Wimbledon, respectively, in League Two.
