The Magpies will look into allegations after a pre-season friendly in Netherlands, in which the two teams drew 0-0, was reportedly marred by some sections of the crowd
Alan Pardew's men, who finished in an impressive fifth place in the Premier League last season, were in Netherlands as part of their pre-season plans.
The Magpies played out a goalless draw with Den Haag although they came close to a win, with Shola Ameobi netting before seeing his effort ruled out for offside.
Yet there was more bad news for Newcastle after allegations emerged that racist chanting had occurring during the game.
The club have since responded to events by issuing a statement confirming that they will be looking into the matter, which read: "In relation to alleged racist chants reported during Newcastle United's friendly against Den Haag today, the club will be raising the matter with officials at Den Haag and the issue will be dealt with privately."
Pardew's side are in pre-season action again on August 11 when they travel to Wales to take on Cardiff City before opening their Premier League campaign at home to Tottenham on August 18.
