The Football Association will consider Newcastle United's call for action to be taken against Manchester City midfielder Nigel de Jong.
The Magpies wrote a 'strongly-worded letter' calling for action after de Jong's tackle left Hatem Ben Arfa with a broken leg following Sunday's 2-1 defeat at Eastlands.
Referee Martin Atkinson took no action against the combative Netherlands international at the time and Newcastle want the FA to take retrospective action.
"We will consider the contents of the letter," confirmed an FA spokesperson.
Ben Arfa is facing months on the sidelines after suffering fractures to his left tibia and fibula and the Magpies have called for strong action.
A club statement read: "Newcastle United FC have written a strongly-worded letter to the FA in relation to the tackle by Manchester City's Nigel de Jong on Hatem Ben Arfa in Sunday's Premier League fixture, which resulted in Ben Arfa sustaining a broken tibia and fibula of his left leg.
"The club has asked the FA for the appropriate action to be taken against de Jong for the tackle which in the club's opinion was unnecessary and used excessive force.
"Newcastle United will also be writing to the appropriate body regarding the performance of the match officials, specifically the referee, in relation to a number of incidents during the game including the tackle on Ben Arfa."
