Hurricanes captain Eric Staal had surgery Tuesday to repair a core muscle injury and is expected to make a full recovery by the start of the season, the team announced.

Sidney Crosby won't need surgery on his ailing right wrist, the Penguins announced Tuesday. 

"After seeking additional medical advice, doctors have decided not to perform surgery on Sidney Crosby's wrist," GM Jim Rutherford said in a statement. "Sid will continue treatments and be evaluated regularly while he prepares for training camp in September."

Penguins captain Sidney Crosby will have arthroscopic surgery on his right wrist to repair damage that "impeded his performance in the postseason," the Pittsburgh Post-Gazette has reported, citing a source close to the star.

Predators forward Mike Fisher has a ruptured Achilles tendon that likely will cause him to miss at least the start of the upcoming season, according to an ESPN.com report.

In a statement released Monday, Predators GM David Poile said Fisher underwent surgery Thursday after rupturing the tendon during a training session.

"We expect Mike to make a full recovery in four to six months, and look forward to his return to the ice," Poile said.
