All Kirill Marchenko could do was stare out from the penalty box in utter disbelief. His accidental tap of a puck over the glass Thursday night at Nationwide Arena led to a key penalty followed by Aleksander Barkov's winning goal for the Florida Panthers in a 1-0 overtime victory that dealt the Blue Jackets a fifth straight defeat.

Captain Aleksander Barkov scored a power-play goal 29 seconds into overtime and Sergei Bobrovsky made 25 saves to fuel the visiting Florida Panthers to a 1-0 victory over the Columbus Blue Jackets on Thursday.
