Jonas Brodin has been advised by the Wild medical staff to rest a lingering lower-body injury for an undetermined amount of time.
The defenseman missed his ninth straight game when Minnesota visited the Columbus Blue Jackets on Thursday.
"He's got a lower body that keeps getting aggravated," Wild coach Dean Evason said. "The medical staff feels it's best to give him some time to rest here. I don't know, we don't know how long that will be, but we'll get him right so we can get him back."
Brodin has not played since he was injured during a 3-2 loss to the Arizona Coyotes on Feb. 6, though he finished the game.
"He's a big part of our hockey club, for sure," Evason said. "People, a lot of people, not one person, has to step up to the plate, but yeah, he eats a lot of minutes, obviously, but we're confident that our group will step up and get the job done in his absence."
Dakota Mermis made his season debut; the defenseman was recalled from Iowa of the American Hockey League under emergency conditions Wednesday.
Marcus Foligno returned after the forward missed four games with an upper-body injury.
"I feel really good, 100 percent," Foligno said. "Being out for a while, anytime a regular goes out and gets a chance to get back in, then you want to be able to make an impact right away."
