The Sweden international suffered a calf injury whilst warming-up for Saturday's Primera Division clash with Athletic Bilbao and, after being replaced in the line-up by Bojan Krkic, underwent initial tests on Saturday.

According to the Barca website, those tests confirmed that Ibrahimovic has suffered a small tear in his right calf and is out of the return meeting with Arsenal and is a doubt for next weekend's 'Clasico' with Real Madrid at the Bernabeu.

Ibrahimovic scored both goals as Barca drew the first leg of their quarter-final tie with Arsenal 2-2 at the Emirates Stadium last Wednesday, taking his tally to five goals in four games.

Centre-back Gerard Pique, who is suspended for the Arsenal match, is also a question mark for the match against Madrid as he suffered a thigh injury that could keep him sidelined for up to seven days.
