The Magpies have written to the FA to ask them to look into the incident, which went unpunished by match referee Martin Atkinson.
A club statement said: "Newcastle United have today written a strongly worded letter to the Football Association 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."
