Barca's midfield dynamo could be sidelined for up to two weeks...
According to El Mundo Deportivo, influential playmaker Xavi has been ruled out of the tie against the German outfit after picking up a thigh injury during training on Tuesday.
The club have yet to confirm the injury but it is suspected that the 30-year-old could be out of action for around 10 to 15 days.
Coach Pep Guardiola will now have to decide how to line up his midfield against Stuttgart as Seydou Keita has yet to be confirmed fully fit at the end of Tuesday's workout session eventhough he managed to train with the rest of the squad.
Barcelona and Stuttgart are locked at 1-1 after the first leg encounter in Germany three weeks ago.
