Vilmanis (undisclosed) will not return to Saturday's game against the Capitals, per Panthers TV Rinkside Reporter Katie Engleson.
Vilmanis was ruled out during Saturday's second period. The 22-year-old winger was gaining momentum before going down, as he compiled four points in Wednesday's 5-3 win over the Blackhawks. His status will be closely monitored ahead of the second half of Florida's back-to-back Sunday.
