Madrid  - Argentina striker Lionel Messi was injured in training Friday, but it was unclear whether it would affect his participation in Barcelona's game against Getafe on Sunday.

"Messi finished the training session with pain in the quadriceps muscle in his right leg," Barcelona's club doctors said in a statement.

"After carrying out different tests, a muscular injury has been discounted. In spite of this, the participation of the player in forthcoming matches depends on the clinical evolution of this problem, in order to avoid a situation of risk."

It was not immediately clear if Messi, 21, would be fit for either Sunday's home game against Getafe, or for Wednesday's Champions League clash away to Sporting Lisbon.

The striker has suffered various muscle injuries since making his Barca debut in 2004, and missed the 2006 Champions League final through injury.

Barca - who are three points clear at the top of La Liga - also have Gabriel Milito, Eric Abidal and Andres Iniesta injured at the moment. (dpa)
