Barcelona striker Zlatan Ibrahimovich is an injury doubt for his side's Champions League quarterfinal return leg against Arsenal on Tuesday night.
The Swede, who scored both of Barcelona's goals in their 2-2 draw in Arsenal's Emirates Stadium last Wednesday, suffered an injury to his soleus muscle while warming up ahead of Saturday's BBVA Primera Liga game against Athletic Club Bilbao, which Barcelona won 4-1.
Barcelona coach Pep Guardiola was forced to change his starting 11 before the game kicked off, drafting Bojan Krkic into the side and giving Thierry Henry a place on the bench, when the Frenchman was due to watch the game from the stands.
Ibrahimovich will undergo tests on Sunday but must be considered doubtful for Tuesday's game and perhaps Barcelona's game against Real Madrid in the Santiago Bernabeu Stadium next weekend.
Barcelona will also be without suspended defensive duo Carles Puyol and Gerard Pique against Arsenal, while Andres Iniesta is doubtful with a muscle problem.
