Sanderson (lower body) won't play versus the Predators on Saturday, per the NHL media site.
Sanderson will miss his fourth straight game. The 24-year-old defenseman's next chance to play is Monday versus the Devils in the first half of a back-to-back set. Since that game is on the road, the Senators may be cautious with their top blueliner and hold him out until Tuesday's game versus the Blues.
