Barcelona midfielder Rafinha missed training on Tuesday afternoon with a virus, potentially ruling him out of Wednesday's Champions League clash against Paris Saint-Germain.
The 21-year-old did not play in Barca's 5-1 win over Espanyol at the weekend, but had been expected to feature against the French outfit.
However, a virus forced Rafinha to miss the club's final training session and it is now unlikely that the midfielder will take part at the Camp Nou.
Barcelona need to win against PSG if they are to top Group F.
