FC Barcelona announced on Wednesday that Alex Abrines has suffered a left knee injury and is expected to miss time.
As the club also said, Abrines will undergo further medical tests that will show for how long he will remain out of action.
The Spanish forward played with FC Barcelona in the Spanish Super Cup last weekend, where the Catalans lost to Real Madrid in the Final.
Following his injury, his presence in the opening day of Liga Endesa is in jeopardy, with FC Barcelona facing Murcia on Sunday.
