Hartman (upper body) is expected to remain on the shelf versus the Lightning on Thursday, Michael Russo of The Athletic reports.
Hartman will be out of action for a third consecutive game due to his lingering upper-body injury. Still, the fact that the 30-year-old winger is traveling with the team should bode well for a short-term absence. For now, Marco Rossi and Joel Eriksson Ek figure to fill the top-six center roles for the Wild.
