Arsenal attempted to prise him out of Alan Pardew's grasp when the Gunners tabled a £10million bid last month.
Mike Ashley dismissed the offer out of hand, and even though Arsenal made it known the offer was "take it or leave it - we won't be back", Cabaye held out for another offer.
He refused to play for the club; was dropped by France; and now the transfer window is over the ball was very much in Cabaye's court.
What could he do? He is desperate to go to the World Cup in the summer and he knows he is now in a NO WIN situation.
Pardew had previously diplomatically declined to go into detail over the situation, but having seen Cabaye make a public apology over the stand-off earlier this week, revealed the player has been disciplined and in the process, issued a tacit confirmation.
Alan Pardew: "He has also been disciplined for his actions this week and he accepted that in good faith, and therefore we move on now.
"As far as I'm concerned, especially on Saturday, it would be nice if our 51,000, 52,000 [fans], whatever it is, give him the support he now deserves for at least apologising for that and taking the punishment that came with it.
"That's a signal to the players here and players elsewhere as well that until the contract is signed with another club, there is a responsibility to the club you are at.
"As I say, he has accepted that in good faith and he was brilliant last week.
"He's a fantastic player, not just for us, but for France, and I know he is going to have a great season.
"What Newcastle fans want to see him do is pull the that shirt on and give everything he's got. I think he did that against Aston Villa, and that's the signal for going forward whenever you get a scenario like that.
"I don't really want to comment on it anymore. It's now dead and gone and now we just want, and I want, Yohan to perform to the best of his ability.
"He has been brilliant this week again. Trust me, he's a fabulous player and very important to us.
"His performance last week spoke a thousand words. He didn't really need to do that [apologise] in the week in terms of winning over our fans, I don't think. His performances will do that and his endeavour."
Cabaye is not happy with the club and he believes he deserves to be involved with Champions League football, and with his ability, he is right.
He also knows it won't happen with Newcastle, not under Mike Ashley, that is a fact.
He will have to wait until the January window to move on, if anyone wants him, but he has many bridges to build as regards the supporters.
As for the club - they should have fined him a weeks wages for every game he refused to play, but they let him get away with it!
