The FA and Crystal Palace are working together to identify the person responsible for throwing an object at Fabricio Coloccini.
Crystal Palace and the Football Association (FA) are attempting to establish which individual threw an object - believed to be a coin - from the crowd, which struck Newcastle United's Fabricio Coloccini.
The incident occurred during Wednesday's 1-1 Premier League draw between the two sides at Selhurst Park.
As Newcastle celebrated Papiss Cisse's opener in front of the home end, an object from the crowd struck Coloccini in the face.
Newcastle boss John Carver was left furious, claiming Coloccini could have been blinded, while Palace manager Alan Pardew said it was out of character for a usually well-behaved bunch of supporters.
When contacted by Perform, the FA said it had been in touch with Palace about the matter to try and identify the culprit, but that it was unlikely the club would be charged.comments
