The 26-year-old, who was involved in a collision on June 3, will spend the next three days at home before beginning his rehabilitation from spinal injuries
The Le Havre youth academy product, who turned 26 on Friday, suffered spinal injuries on June 3 after the car in which he was travelling crashed on the A28 motorway, some 60 kilometres north of Rouen.
However, Anin's sister, Soukhy, has now revealed on Twitter that her brother has been finally discharged from hospital.
"Friday, Saturday, Sunday [at] home and then Monday off to rehabilitation," she wrote. "I'm so happy I could cry."
Anin's mother told L'Equipe that it is too early to tell if her son will recover the use of his legs.
"The doctors told us that we would only know after the rehabilitation, so we will hope with all our hearts," she explained.
Meanwhile, Nice boss Claude Puel said that Anin was in good spirits when he visited him last week.
"His morale is good," the 51-year-old coach stated. "He's very brave and is a fighter."
Anin joined Nice from Sochaux on a four-year contract during the January transfer window of 2012.
