Couturier came down with an illness that caused him to leave Wednesday's practice prematurely, Adam Kimelman of NHL.com reports.

EDGE Analysis

The Flyers will go to work against the Panthers on Thursday, and there's bound to be clarification on the two-way pivot's status ahead of that contest. However, Michael Raffl (lower body) and Travis Konecny (lower body) are also ailing, so a call-up from AHL Lehigh Valley could be forthcoming if Couturier sits out for the first time in 2017.
