Carolina forward Max Pacioretty left the game with 20 seconds remaining in the third period. He grabbed his right leg after making a pass in the offensive zone and required help leaving the ice. The 34-year-old missed the previous two games with a lower-body injury and the first 38 this season due to an Achilles injury.
"It doesn't look good, but we don't know," Brind'Amour said. "We know what kind of player he is, and we got a glimpse of it. [His return] was exciting; it's the kind of player we needed. Hopefully it's not as bad as we think, but I'm not too optimistic right now."
Kirill Kaprizov scored his 100th NHL goal, and Marc-Andre Fleury made 24 saves for the Wild (25-15-4), who won their previous three games.
Minnesota was assessed seven minor penalties in the game, including three in the first period, and was 5-for-7 on the penalty kill.
"It put us on our heels," Wild coach Dean Evason said. "Then we still get through it and still played well, but [the penalties] kept coming. Obviously, they get enough looks and they're going to score some goals."
Kaprizov gave Minnesota a 1-0 lead with a power-play goal at 7:11 of the second period, scoring on the rebound at the right post after Andersen stopped Mats Zuccarello on a sharp-angle shot.
"I think 5-on-5 we were actually pretty good," Wild forward Joel Eriksson Ek said. "For us to get the lead, then they have to chase a little bit."
