Barcelona full-back Adriano is doubtful for the Spanish Super Cup second-leg against Atletico Madrid on Wednesday due to a hamstring injury.
The Brazilian scored the only goal as Barca moved back to the top of La Liga on Sunday nght with a 1-0 win away at Malaga.
However, he had to be withdrawn at half-time to be replaced by compatriot Dani Alves.
"The tests carried out have revealed the player has a strain in his right hamstring," the club said in a statement on Monday.
"His recovery will determine whether he is available for the next match."
