Barcelona defender Adriano could miss the rest of the season with a hamstring injury he suffered in Wednesday's Copa del Rey defeat to Real Madrid
The Brazilian was replaced just before the end of the match, which Madrid won 1-0 after extra-time.
Scans have shown he has damaged his hamstring which will sideline him for four weeks.
That means Adriano is set to miss Barca's final six league matches, with the season finishing on the weekend of May 21/22.
He could potentially be available to coach Pep Guardiola if the club reach the UEFA Champions League final on 28th May.
Barcelona are already short of options at left-back with Eric Abidal sidelined for the rest of the season after undergoing surgery on a tumour on his liver.
