Bayern's Boateng sidelined with adductor muscle injury

BERLIN, April 27 (Reuters) - Bayern Munich's Germany defender Jerome Boateng suffered an adductor muscle injury in Wednesday's Champions League semi-final, first leg loss to Real Madrid, the club said.

The German champions did not indicate how long Boateng would be out of action as they prepare for the rest of the season, including next week's Champions League return in Madrid plus the German Cup on May 19, and with the World Cup starting in June.

"Boateng suffered a structural injury in the adductor muscle of his left thigh," Bayern said in a statement on Thursday, without providing any more details.

Bayern's Dutch winger Arjen Robben, who also came off injured in their 2-1 home defeat by the Spaniards, was diagnosed with a thigh muscle problem.

Javi Martinez, the third Bayern player who had to be substituted on Wednesday, picked up a minor head injury and the Spain international will miss a couple of days of training.
