Rolston, whose 25 goals and 46 points are tops on the team, saw a doctor instead of practising. He wasn't feeling better but tests didn't reveal anything, assistant general manager Tom Lynn said. Rolston is questionable to play in Thursday's game against Florida.
Defenceman Kurtis Foster, however, participated fully in Wednesday's practice and probably will play against the Panthers. He hasn't suited up since hurting his knee on Jan. 16 against Edmonton.
Also Wednesday, the Wild sent right-winger Joel Ward back to the minors for the fourth time this season. Ward played briefly in Tuesday's game at Dallas.
