Suter has not missed a game since signing with the Wild in July 2012, playing all 153 games in the regular season and 18 games in the Stanley Cup Playoffs.
The defenseman is sick; the Wild aren't sure if it's the flu or the mumps.
"We're hoping it's just illness, but we won't know until we get the blood work," coach Mike Yeo said. "He doesn't have swollen glands, but there are a couple of symptoms he has that would make us concerned that it could be that [mumps]."
Suter leads the NHL in average time on ice this season at 29:19 per game. His plus-10 rating is best on the Wild and his 12 assists are tied for the team lead.
