Vancouver winger Daniel Sedin had surgery to repair a herniated disc in his lower back but Canucks general manager Brian Burke is optimistic the Swede will be ready for training camp in September.
Burke said the Monday night operation was not disclosed beforehand to avoid a "phalanx of cameramen and reporters at the hospital", which Burke didn't identify.
"Everyone thought (the surgery) went extremely well," Burke told CKNW, a Vancouver radio station.
Sedin was injured while playing for Sweden at the world hockey championships in Germany.
Burke says the 20-year-old will likely be ready for training camp in September and he doesn't expect the injury will become a chronic problem.
"The time frame, whatever it is, for mild exercise, then more rigorous exercise, then full-go, then contact, is comfortably within training camp guidelines," said Burke. "So we expect him to be on the ice at training camp without difficulty.
"They (doctors) were pleased with the results and I have to take that at face value. I think we're happy with everything."
Sweden officials reported Sedin had suffered a hernia during the worlds, but the Canucks announced in Vancouver that he had a lower back strain.
Sedin actually suffered a herniated disc in his back, Burke said Monday.
Canucks medical trainer Mike Burnstein was dispatched to Germany to examine Sedin, and the pair returned to Vancouver last Tuesday.
Sedin had consulted several back specialists since then.
His twin brother and Canuck teammate, Henrik, remained with the Swedish team through their bronze-medal victory Sunday against the United States.
