Detroit Red Wings forward Drew Miller had surgery to reconstruct his left ACL and will miss 4-6 months and defenseman Niklas Kronwall is out 2-4 weeks after arthroscopic knee surgery, according to the Red Wings website.
Miller, who hasn't played since Jan. 10, has one goal and one assist in 28 games this season.
"He's an elite penalty killer, there's no question," coach Jeff Blashill told the Red Wings website. "That doesn't mean that our penalty kill can't do a great job. We've got guys, we've been using (Justin Abdelkader) more, we've been starting to use Dylan Larkin more, (Tomas) Jurco at different times has had reps on the PK in practice. We're going to have to find a mix of guys that can get it done."
