Wladimir Klitschko OK after operation

BERLIN -- Wladimir Klitschko's manager Bernd Boente says the WBA and IBF heavyweight champion is recovering well after undergoing an operation to remove a kidney stone.

Boente told German news agency dapd that Klitschko could leave the Duesseldorf hospital after the surgery on Saturday.

Klitschko is scheduled to fight French challenger Jean-Marc Mormeck in Duesseldorf next Saturday. Boente said the bout was still on as long as there were no further complications.

The 35-year-old Klitschko suffered abdominal pains at his training camp in Austria on Friday. He was taken to Innsbruck for treatment before being transferred to Duesseldorf.
