Ludovic Giuly is a doubt for FC Barcelona's visit to FC Shakhtar Donetsk on Matchday 6.
Giuly played 28 minutes of the game at Camp Nou between Barcelona and an all-star side, the proceeds of which went to an AIDS charity. The forward was substituted after complaining of pains to his right hamstring and tests showed that he had stretched the muscle.
Giuly has been told to rest for the next seven days, which rules him out of Saturday's league match against Málaga CF and puts in doubt his availability for next Wednesday's Group F match in Ukraine. Barcelona need to beat Shakhtar and hope leaders AC Milan slip up against Celtic FC to finish as group winners.
