Football's Kick It Out organisation believes the game will have suffered another "depressing development" if racist chanting allegations against two players are proven.
West Ham's England striker Carlton Cole claims to have been the victim of racist 'monkey' taunts from Millwall fans while Jason Price was also targeted by home fans during the Carling Cup match between both clubs at the Boleyn Ground on Tuesday night. The game was marred by three pitch invasions with fans also confronting police inside and outside the ground.
Lord Herman Ouseley, founder and chair of Kick It Out, football's equality and inclusion campaign said: "If there were racist chants being directed at any of the players involved, then it's a depressing development on an already shameful night."
He added: "Football in this country has come a long way in recent history. Our vying for the World Cup bid is a prime example.
"Incidents like this, however, demonstrate the work still to be done. With the help of our partners, and the fans, we're determined to continue making football a racism free environment."
Cole's allegations have yet to be proven as both the police and the football authorities investigate the appalling scenes which marred the second round tie which West Ham won 3-1.
The Football Association will wait to see if Cole's claims are included in the referee's report before deciding on what action to take.
