Chisholm wasn't on the ice for Wednesday's practice due to an illness, Michael Russo of The Athletic reports.
Chisholm appeared in 29 regular-season games for the Wild last year after they acquired him from Winnipeg. In those outings, the 24-year-old blueliner recorded three goals and five assists, including five power-play points. While he might struggle for regular minutes with the man advantage this year, in part due to the return of Jared Spurgeon, Chisholm should be a regular in the lineup. If he can't play Thursday against the Jackets, Jon Merrill figures to step into a third-pairing role.
