Sanderson didn't skate Wednesday due to a minor undisclosed issue, Claire Hanna of TSN reports.
Head coach Travis Green hesitated to label the reason for Sanderson's absence as an injury, so fantasy managers likely shouldn't worry. Sanderson isn't expected to play in either of Wednesday's split-squad preseason games against Toronto. Still, it wouldn't be surprising if he was fine for the start of the 2026-27 campaign.
