Cernak (undisclosed) was hurt Wednesday versus the Sabres and is unlikely to play Thursday versus the Blue Jackets, Benjamin Pierce of the Lightning's official site reports.
Cernak got hurt in the second period after colliding with the glass near the bench. Max Crozier or Emil Lilleberg will draw into the lineup to cover Cernak's absence. Cernak's status for Saturday versus the Red Wings has yet to be determined.
