Detroit Red Wings captain Henrik Zetterberg had back surgery Friday, and the team expects him to be evaluated again in about eight weeks.

Zetterberg played through pain and scored a goal in Sweden's opening victory over the Czech Republic last week at the Sochi Olympics, but that was his only appearance before he left because of a herniated disk.

Zetterberg has 16 goals and 32 assists in 45 games for the Red Wings this season. Detroit is fighting for a playoff spot in the Eastern Conference, and it now seems the Red Wings will be without the 33-year-old center for most if not all of the stretch run.

The Red Wings say the operation was performed by Dr. Frank Cammisa in New York.
