Ibrahimovic, who opened the scoring in the 4-1 victory with his fourth goal in successive league matches this season, was replaced in the 53rd minute after picking up the injury.

The Swedish international will undergo more tests today to determine the extent of the injury and whether he will be sidelined for any length of time.

Barca travel to Malaga in La Liga this weekend and then host Dynamo Kiev in the Champions League next week.

Ibrahimovic said after the Racing match: "I don't know yet if I will be able to play in Malaga. I think I'm ok, maybe I need a little treatment. I'm calm."
