Paris Saint-Germain have confirmed striker Edinson Cavani has a hip injury, but he has not been ruled out of Tuesday's Champions League trip to Manchester United.
Cavani suffered the injury in Saturday's victory over Bordeaux, in which he scored the only goal from the penalty spot, and coach Thomas Tuchel was pessimistic about the Uruguay international's chances of being available for the last-16 match at Old Trafford.
"There's no good news for Edi this morning. He had some tests and there will be more to come," Tuchel told Telefoot on Sunday.
PSG then released a short statement revealing examinations showed Cavani has a hip injury, although they gave no timescale for his recovery.
"The treatment of this injury and the length of his unavailability will depend on the evolution of the injury over the coming days," PSG said in a medical update.
Neymar is already out of the United game and reports in France have suggested Cavani may not be ready to play in the return leg in Paris on March 6.
Although Marco Verratti played 59 minutes against Bordeaux to boost hopes he could face United after recovering from an ankle injury, PSG have been dealt a further blow.
The club announced Thomas Meunier has a concussion, with the right-back unavailable to take on Ole Gunnar Solskjaer's side as a result.
An official statement read: "Thomas Meunier's neurological examination confirmed a light concussion. Thomas will be unavailable until his next neurological consultation at the end of the week."
His absence will pose a further selection dilemma for Tuchel, who has been using right-back Dani Alves in midfield of late.
