Barcelona breathe as Lewandowski's injury just a knock

Bad news for Barcelona with 'El Clasico' just around the corner. Robert Lewandowski, the only No.9 in the squad, went off injured in the 'Cules' 0-1 win against Porto at Do Dragao.
The Pole was forced off in the first half after taking a blow to his left ankle in an action in which Carmo tried to win the ball by tackling Lewandowski.
Finally, Xavi Hernandez decided to replace him against Oporto and brought on Ferran Torres just after the half-hour mark.
At half-time against Porto, 'COPE' reported that the Polish striker only has a serious knock, and is therefore not injured.
