Barton travelled to London on Wednesday for talks after the Loftus Road club was given permission to speak to the 28-year-old, still available on a free transfer after falling out with the Newcastle hierarchy earlier this summer.
The midfielder continues to state that he wishes to remain at Newcastle, but with only one year left on his contract and no new deal forthcoming, he believes he is being forced out.
"Going for a medical now, still no contract offer from NUFC.......think that just about makes my mind up," Barton wrote on his Twitter account.
"Don't want to leave Newcastle........I've made that clear but my hands are tied."
