General manager Ken Holland told the Red Wings website July 1 that he expects Zetterberg to play this season.
"The last I talked to him, I think he's planning on playing," Holland said. "Obviously his back is going to determine whether he can or he can't. Do I have a clear green light? I'm expecting him to play. Do I have a clear green light? No, I don't know that I've got a clear green light."
Zetterberg, the Red Wings captain, had 56 points (11 goals, 45 assists) last season, second on Detroit to forward Dylan Larkin (63 points).
Zetterberg said before last season ended he expected to return and has not said those plans have changed.
"For me it's going to be the same as I've been doing the last couple of years," Zetterberg said April 3. "I will go into the offseason and try to have a good summer, work on my health, and hopefully I can come back and be better."
Zetterberg had surgery to repair a ruptured disk in 2014, when he was unable to continue to play for Sweden at the Sochi Olympics. He has missed five NHL games since then, all in 2014-15.
"Ever since my back surgery, that's been one of the goals, to be able to play as many games as possible," Zetterberg said. "But in the same way, you want to be able to do something out there too. You don't just want to put on the skates. You want to be able to produce and help your team."
Detroit has not made the Stanley Cup Playoffs the past two seasons and has not won a series since 2012-13.
"It's no fun losing, but I still have a lot of fun playing hockey and being around this group of guys," Zetterberg said in April. "Obviously, it would be a lot more fun if we'd still be playing after this weekend. In decision-making, I don't think that has anything to do with it. Health is the key. If I'm not healthy, it's over."
Zetterberg has 960 points (337 goals, 623 assists) in 1,082 games with the Red Wings and 120 points (57 goals, 63 assists) in 137 playoff games. He won the Conn Smythe Trophy as MVP of the playoffs in 2008 when he helped Detroit win the Stanley Cup.
