Barcelona are waiting to find out if striker Robert Lewandowski will be fit for the Copa del Rey final and the Champions League semi-final after he appeared to suffer a hamstring injury Saturday.
The Polish forward, Barca's top scorer this season, was taken off in the final stages of his team's 4-3 win against Celta Vigo, which put the Catalans seven points clear of second-placed Real Madrid.
Barca face Mallorca Tuesday in LaLiga and then Real in the Copa final on April 26, before hosting Inter Milan in the Champions League semi-finals on April 30.
"We have to wait...from my experience we wait until tomorrow," said Barca coach Hansi Flick, whose side are chasing a potential quadruple of trophies.
Spanish media reported Lewandowski could be out for three weeks, which would put him at risk of missing both legs of the Champions League semi-final.
Spaniard Ferran Torres is set to take Lewandowski's role in the attack if the 36-year-old is sidelined.
