Midfielder Xavi may struggle to be fit in time for Barcelona's crucial Champions League match with AC Milan later this month following confirmation his hamstring injury is set to sideline him for up to 15 days.
The Spain international had only recently come back from a similar injury when he complained of discomfort following Wednesday's Copa del Rey semi-final second-leg defeat to Real Madrid.
According to a Barcelona statement on Friday, Xavi is likely to be out of action for "10 to 15 days".
That means that not only will the 33-year-old sit out Saturday's league clash with Madrid as expected, and next weekend's visit of Deportivo La Coruna, but he may now also miss the Champions League last-16 second leg against Milan on March 12.
Milan lead 2-0 from the first leg at the San Siro.
