Stephen Weiss was out for the third consecutive day with an undisclosed lower-body injury Saturday night.
Weiss practiced Thursday morning but then informed Panthers head coach Kevin Dineen later that afternoon he couldn't play against the Senators. "He had been a little tender for a couple days," Dineen said. "You always test how you feel and if it's heading in the right direction. I don't think it was. He needed to step back and start feeling healthy. Weiss in particular has struggled thus far in this shortened 48-game season.
