The Senators could be without star centre Jason Spezza when they host the Thrashers on Thursday night.
Spezza missed practice Wednesday after sustaining a slight groin pull in Tuesday's skate. Spezza is second on the Senators with 13 points (1-12) in 10 games.
"It happened yesterday and right now it doesn't feel that good," Spezza told reporters Wednesday. "We're just going to kind of take it day by day."
