The FA will shortly announce the findings of their investigation into the trouble which flared at West Ham's Carling Cup match against Millwall.
Newspaper reports have claimed both clubs will be charged by the FA in connection with the crowd trouble which marred the match at Upton Park on August 25.
A statement from the FA said: "The FA's extensive investigations into the events at the recent West Ham versus Millwall fixture are drawing to a close.
"CCTV footage from approximately 47 cameras inside Upton Park is still being examined along with other lines of enquiry.
"Both clubs have co-operated and provided assistance in relation to the enquiry and the FA expects to be in a position to confirm the outcome of the investigation in the coming week.
"The FA has also been liaising closely with the Metropolitan Police in connection with the disorder outside the ground, whilst West Ham published photographs in Saturday's matchday programme to assist in the identification process."
