Lightning's Erik Cernak: Sustains undisclosed injury

Cernak (undisclosed) exited Thursday's game versus the Ducks and won't return, Gabby Shirley of FanDuel Sports Network Florida & Sun reports.

Cernak lasted just one shift into the contest before his departure. The Lightning have just six healthy defensemen on the roster, so if Cernak can't suit up Saturday versus the Red Wings, a roster move will likely be necessary.
