Markstrom (undisclosed) is considered day-to-day and will miss Tuesday's road clash against the Blue Jackets, per Rob Darragh of the Panthers' official site.
Markstrom exited Monday's contest with some tightness, but is expected to have avoided injury. Tuesday's absence is likely just a maintenance day for the 36-year-old netminder, and we could see him suit up again as early as Thursday against the Canucks. For Tuesday's clash Akira Schmid will draw the start and Cooper Black will back up.
