Troyes were in Spain on a training camp when the 26-year-old had the problem and he will need a month to recover.
The 26-year-old has suffered a thigh injury and will have further tests on Thursday to show the full extent of the damage.
The news will be a bitter blow for coach Faruk Hadzibegic (pictured) as Nivet is a key member of his struggling squad.
Hadzibegic's troops are stranded at the foot of the table and are still seven points away from safety.
The loss of former Chateauroux star Nivet is yet another blow for the strugglers in their battle against relegation.
