Sanderson departed Saturday's game versus the Maple Leafs due to a lower-body injury, Julian McKenzie of The Athletic reports.
Analysis:Sanderson is set for further evaluation Sunday, and the team will know more in the next few days. The defenseman was never seemingly fully healthy after dealing with the injury throughout the preseason, but this is the first time the Senators have put a label on the issue. His status for Monday's game in Boston remains up in the air.
