Sissons (lower body) was placed on injured reserve on Thursday and is considered week-to-week, per David Alter of The Hockey News.
Sissons suffered his lower-body injury during Sunday's clash against New Jersey and was ultimately deemed week-to-week Monday. Across 19 outings this season, the 33-year-old forward posted two goals and six points. In his absence, Brendan Brisson has been called up from AHL Toronto to serve as a depth option.
