Zetterberg had surgery in February to remove part of a disk that was rubbing on a nerve. He missed 24 games and had to withdraw from Sweden's team at the 2014 Sochi Olympics because of the injury.
"That part of the back is healed," Zetterberg said, according to MLive.com. "I feel good. I can do everything on the ice and in the weight room. I had a really good summer, workout-wise, so I look forward to seeing what results that will give me."
Zetterberg scored 16 goals and recorded 32 points in 45 games last season. The Red Wings made the playoffs for the 23rd consecutive year, but fell in the first round to the Boston Bruins.
