The Wild filled the holes in their lineup ahead of Game 3 in their first-round series against Dallas, but they didn't stay at full capacity for long.
Joel Eriksson Ek returned for a 19-second shift Friday night at Xcel Energy Center before leaving for the rest of the game.
"It's sad, right? Disappointing, obviously," Wild coach Dean Evason said after the 5-1 victory. "We all know who he is, outside and more importantly inside and his will to get back out there with his teammates was tremendous. So, yeah, it's a tough one, for sure.
"Obviously he's been looked at. He's going to be looked at tomorrow, probably a little more extensively and then we'll know more."
This was Eriksson Ek's first action since the center was hit by an Evgeni Malkin shot on April 6 at Pittsburgh and shelved because of a lower-body injury.
Eriksson Ek, who finished third in goals on the team (23) and had the second-most assists (38) for a career-high 61 points in the regular season while being a force defensively, took part in the pregame warmups and was announced as part of the Wild's starting lineup alongside his usual linemates Matt Boldy and Marcus Johansson.
He was one of three regulars the Wild added after going 1-1 in Dallas to start the series.
Ryan Hartman suited up after missing Game 2 because of a lower-body injury.
