BERLIN, April 23 (Reuters) - Bayern Munich defender Holger Badstuber has been ruled out for three to four months after tearing a thigh muscle in their Champions League quarter-final victory over Porto this week that will require surgery, the club said on Thursday.
The Germany defender, who had only returned this year after more than two years out with a double ligament tear, will leave for the United States in the coming days where the operation will take place.
"Obviously I am bitterly disappointed," Badstuber said in a statement.
"I am, however, optimistic and will return fully healthy.
