Barcelona assistant head coach Jordi Roura told the club's official website that the leg injury was nothing serious, as ESPN reported.
The Argentina forward is unlikely to miss the Champions League last-16 tie against AC Milan, but other clubs in the tournament are waiting anxiously on news of their injured players.
Here we take a look at the injury situation for some Champions League competitors.

The Spain No. 1 broke a bone in his hand during the 1-1 draw with Valencia in the Copa del Rey quarterfinal last week and has been ruled out for up to 12 weeks, reports Goal.com.

Real have moved to cover Casillas' absence for the next three months by signing Diego Lopez from Sevilla.

The 35-year-old picked up a thigh muscle problem during the goalless draw with Sampdoria in Serie A two weeks ago and has been ruled out for a month.
The news of Ambrosini's injury comes after fellow midfielder Nigel de Jong was ruled out for the rest of the season with an Achilles' tendon problem.

The Scotland international made his first appearance since December 2011 when he played in the group-stage match against Galatasaray in September, but the chronic condition has not cleared and needs further treatment.
Fletcher was an unused substitute in United's Champions League triumph in 2008 but missed the following year's final defeat to Barcelona through suspension.
Fletcher featured five times for United during the group stages this season.

Midfielder Christoph Moritz picked up a knee ligament tear during a friendly win over Al-Sadd earlier this month and will be out for five weeks, according to a report on uefa.com.
