Queens Park Rangers have promised to ban any supporters who threw missiles at Chelsea players during Sunday's Premier League clash at Loftus Road.
Chelsea won a hotly contested West London derby 1-0 thanks to an 88th-minute goal from Cesc Fabregas, who celebrated by leading the rest of the players close to home fans -- and Branislav Ivanovic was allegedly hit on the head by a cigarette lighter.
The Press Association reports that the Football Association will be contacting both clubs for their observations, though QPR are unlikely to face disciplinary action.
But QPR have vowed to take the necessary steps to identify the culprit via CCTV and for them to face a banning order.
A statement released by QPR read: "The club is aware that objects were thrown by a small section of supporters towards the pitch following Chelsea's 88th minute goal.
"The club takes the safety of all supporters and players very seriously and are currently reviewing CCTV footage of the aftermath of the goal in an attempt to identify those responsible.
"Whilst we understand that passions run high during derby fixtures, this is not the kind of behaviour the club condones in any way, shape or form.
"We take a zero tolerance approach to this sort of behaviour and, if the perpetrators are identified, they will be banned indefinitely from the stadium and, where appropriate, we will liaise with the Metropolitan Police.
"The club are awaiting communication from the FA following the referee's report and will work closely with them in ensuring something like this does not happen again.
"We would also appeal to fans with any information regarding yesterday's incident to contact the club, as we feel it's important to identify the perpetrators as soon as possible, as we believe they are not a true representation of the QPR fan-base."
