Barcelona forward Pedro will be out of action for 10 days after injuring his calf on international duty with Spain.
Barca issued a statement saying: "Tests have confirmed that the player has small muscle fibre tears in his left leg."
Pedro scored the winner for world champions Spain in their 1-0 victory over France in Paris on Tuesday which put them back on top of their group in qualifying for next year's World Cup finals.
The 25-year-old was already suspended for next Tuesday's Champions League quarter-final first leg against Paris St Germain, but will now miss Saturday's league trip to Celta Vigo and is a doubt for the visit of Real Mallorca the following weekend.
Pedro is the second Barca player to pick up an injury on international duty this month after defender Jordi Alba suffered a hamstring strain while also away with Spain.
