Marseille have been charged by UEFA after an object was thrown in the direction of Liverpool midfielder Steven Gerrard during Wednesday's Champions League game at Anfield.
Gerrard appeared to be hit by a missile thrown from the Marseille fans' section as he went to take a corner in the first half of Liverpool's 1-0 victory.
UEFA confirmed yesterday the incident was to be included in Portuguese referee Olegario Benquerenca's report as well as the report from UEFA delegate Svein Johannessen.
European football's governing body today confirmed to PA Sport that Marseille will answer the charge at a meeting of UEFA's control and disciplinary panel on December 11.
UEFA also confirmed that the French club have been fined 15,000 euros following a near identical incident at the Stade Velodrome in September.
Liverpool boss Rafael Benitez welcomed UEFA's decisive action although also said he had some sympathy with the French club.
He said: "It is good that UEFA have acted. But the problem is that it is just one person out of thousands who decides to do something like that, so how can you control it? It is not easy to stop these things.
"It is difficult to control everyone, if someone wants to do something like this then it is hard to stop. You can fine the club and look for solutions afterwards, but you cannot control everything. But the response of Gerrard was very good."
Meanwhile, Roma are facing charges from UEFA following crowd trouble at their Champions League match against Chelsea earlier this month.
A UEFA spokesman confirmed that Roma have been charged with ''insufficient organisation'' at the Stadio Olimpico after fireworks were set off at the match on November 4.
There was also fighting between fans prior to kick-off. Roma won the game 3-1. UEFA's control and disciplinary panel will hear the case on December 11.
The Stadio Olimpico has been selected to host the Champions League final in May next year, but UEFA had already voiced concerns over crowd trouble and there is speculation Rome could be stripped of the marquee event.
