Ousmane Dembele has "a complete proximal tear in his right hamstring" as the Barcelona forward suffered a setback in his return from injury.
The 22-year-old has not played since November 27 when he hobbled off in tears in the first half of the 3-1 Champions League win over Borussia Dortmund.
Dembele had been in recovery but aggravated the injury earlier this week in training and Barcelona said in a statement on Twitter a decision on his treatment was still to be made.
"Tests carried out on Ousmane Dembele today have confirmed that he has a complete proximal hamstring tear in his right thigh," the club added.
Dembele signed for Barcelona from Dortmund in 2017 for 105m euros (£89.02m) but his time in Spain has been marred by injuries.
He missed five months of his debut season due to a hamstring problem that required surgery and has made five starts in all competitions this season.
Barcelona are currently second in La Liga, three points behind rivals Real Madrid.
