Florida Panthers star Matthew Tkachuk was taken off the ice in the first period of Thursday's 3-2 overtime win over the Vegas Golden Knights in Game 3 of the Stanley Cup Final by the NHL's concussion spotters.
Head coach Paul Maurice confirmed to reporters after the game the league required Tkachuk be examined after taking a hard hit from Keegan Kolesar that knocked him to the ice.
Tkachuk was initially examined by a team doctor on the bench, returned for a shift later in the first period but left the bench area again and didn't return until early in the second period after clearing concussion protocol.
