Peter DeBoer is shaking up his forward lines for his team's critical Game 5 on Thursday as Joonas Donskoi will start Thursday's game with Joe Thornton and Joe Pavelski on the San Jose Sharks' top line.
Donskoi has been one of the Sharks strongest players in the series against the Pittsburgh Penguins, recording three points in four games, including the overtime winner in Game 3.
Melker Karlsson, who began game 3 and 4 with "The Joes" after Tomas Hertl was sidelined with a knee injury, will play on the second line with Patrick Marleau and Logan Couture.
