Two days after he returned from the Sochi Olympics, Detroit Red Wings captain Henrik Zetterberg has undergone surgery. General manager Ken Holland said that Zetterberg "will be out seven to eight weeks, then he will be re-evaluated." Holland said Zetterberg "had a floating piece of a disk lodged in a nerve in his back." The surgery was performed by Dr. Frank Cammisa this morning at the Hospital for Special Surgery in New York. Holland said Zetterberg should be up and walking by the evening and will remain in New York at least through the weekend for a follow-up visit early next week. "They went in and removed the fragment," Holland said. "The surgery was very successful. They said it was one one disk level that was dislodged, which is good." Assistant general manager Ryan Martin said surgery was decided to be the best solution"for his long-term prognosis." The recovery time pushes Zetterberg past the Wings' regular-season finale on April 13. Holland said maybe Zetterberg can return to practice after the 7-8 weeks, but it hinges on the re-evaluation. There’s no guarantee that he will return for the playoffs, even if the Wings make a deep run. The Wings exit the Olympic break Wednesday at Montreal, clinging to the eighth and last playoff spot in the Eastern Conference. They are trying to extend a 22-season streak of making the playoffs, but that will be all the harder without Zetterberg, their best all-around player. He leads the team with 48 points (16-32-48) and a plus-19 rating in 45 games.
