Chelsea striker Didier Drogba has issued an apology for throwing a coin back into the crowd during their Carling Cup defeat by Championship side Burnley. But he could still be subject to an investigation by the Football Association over the incident.
Drogba was handed a yellow card when he was seen throwing the coin back into the crowd after putting Chelsea in front in the 27th minute.
A spokesman for Chelsea said: "We will deal with this in the usual way. "We are aware there is an incident. But we will not discuss it further until we have seen the referee's report."
Burnley manager Owen Coyle did not see the incident and Chelsea coach Luiz Felipe Scolari said: "I have not spoken with Didier about any problem. "The referee gave him a yellow card but I did not see what happened."
In 2002, Liverpool defender Jamie Carragher was sent off in an FA Cup tie against Arsenal at Highbury after throwing a coin back into the crowd. He received a mandatory three-match ban.
He was also interviewed by police but no further action was taken. However, Carragher was fined by the club and warned as to his future conduct.
Chelsea crashed out of the competition when Brian Jensen saved spot-kicks from Wayne Bridge and John Mikel Obi to send Owen Coyle's side into the last eight 5-4 on penalties.
