Magpies assistant coach Paul Simpson has confirmed the Frenchman is a week or two away from returning to training.
The 29-year-old was signed by the Tyneside club as a player with considerable ability and talent, but the St James’ Park faithful have only seen fleeting glimpses of the versatile attacker in recent times.
Marveaux spent last term on loan at Guingamp in his homeland and picked up a groin injury immediately upon his return to the North East.
However, Simpson has stated that the former Rennes man is closing in on making a return to group training.
"Without wishing to tempt fate, we're in a decent place at the moment,” he told the club’s official website.
"Sylvain Marveaux has come back from France where he's been doing the early stages of his rehab. We're hoping that he'll be back out on the training field in the next week or two.
"He's doing work with the medical department as the first stage of his rehab and we'll then step that up with the other staff and back into the football side of it.”
The 29-year-old has only started 13 games for Newcastle in a couple of years, with his last outing for the club back in March 2014.
Having him back in first-team contention would boost Steve McClaren’s options in wide areas, with Marveaux showing during his time in France that he can be a direct and penetrating attacker.
Newcastle travel to take on West Ham on Monday night, with the club still looking for its first win of the new campaign.
