The duo are believed to have been told they can leave the club early as the Magpies focus on survival with neither player likely to be fit for the remaining handful of games.
Former Rennes man Marveaux had already been written off by former boss Steve McClaren, who felt the player was unable to offer him anything during Newcastle’s relegation battle.
McClaren had at first offered Marveaux another chance at the club after he’d dropped out of favour with previous boss Alan Pardew.
And despite spending five years at Newcastle the winger , who had groin problems, has ended his disappointing spell on Tyneside having made more appearances for French club Guingamp, where he spent last term on loan, than for the Magpies.
Marveaux made just 56 appearances for Newcastle in five years, scoring twice against Arsenal in a 7-3 hammering at the Emirates Stadium and in the Europa League 1-1 draw with Maritimo.
During that stint in Ligue 1 the player had been caught on camera claiming he has been “blacklisted” by Newcastle. Despite being offered a further chance to impress by Rafa Benitez, he leaves the club with three managers opting against using him for first team duty.
Obertan’s season had started with hope after McClaren used him in six fixtures before he picked up a hamstring injury in the first half of the campaign.
He was signed from Manchester United as Pardew had a rare yes from his board when requesting to sign one of his targets.
Obertan made 76 appearances for the Magpies in five years and scored three goals.
The pair’s exits have not been confirmed by the club yet, but it is one of the first signs of a summer shake-up at St James’ Park. Both players were due to be out of contract in June.
