Nice midfielder Kevin Anin could be left paralysed after suffering serious injuries in a car crash on Monday night, according to French media reports on Wednesday.
Anin, 26, suffered an injured spinal column and several fractures to both arms when the car he was travelling in crashed around 60 kilometres to the north-east of the Normandy city of Rouen, his Ligue 1 club revealed.
The sports daily L'Equipe reported that Anin was sitting in the back of the car, a Volkswagen Polo, when the driver lost control of the vehicle, which flipped several times as it went off the road.
Anin was in intensive care in a Rouen hospital on Tuesday night, along with the three other people who were involved in the crash, amid fears that the spinal injury could leave him paralysed.
"The situation seems quite serious. We are worried," said Nice general manager Julien Fournier.
Speaking at a press conference on Wednesday, Nice president Jean-Pierre Rivere admitted that he had not spoken with any of the medical staff treating Anin, but said he feared the outlook was bleak for a player who was linked with Arsenal earlier in his career.
"I'm not here to make a diagnosis, that's not my role," he said. "All we know is that the accident is serious and that it could have consequences for Kevin's life.
"The news that we are getting is not coming from the doctors. It is not reassuring. I fear that his career will be on hold for a long time. But that is not our worry. His health is our priority."
Rivere added that Nice was "a club in a state of shock" since hearing the news.
A talented midfielder, Anin has endured something of a chequered career to date, marred by personal problems.
He moved to Nice from Sochaux in January 2012 for 2.5 million euros ($3.3m) but missed more than four months of the season just finished because of depression and has played just 26 league games for the south-coast side.
