Sandin (illness) didn't practice Saturday and will miss Sunday's game versus the Kings, Bailey Johnson of The Washington Post reports.
Sandin also sat out Friday's 6-2 loss to the Hurricanes. The 23-year-old blueliner has 11 assists and a minus-8 rating through 36 games this season. Ethan Bear will likely continue to work on the second defensive pairing and power-play unit while Sandin is sidelined.
