Since then, the third line has been arguably Seattle's most effective line, with McCann scoring two goals in his last three games.
Tolvanen scored his first goal of the season on Saturday with a redirect in front of Panther's goalie Sergei Bobrovsky.
After being picked up on waivers by the Kraken last season, Tolvanen established himself as a welcomed member to the team's top nine, scoring 16 goals, in 48 games with the Kraken.
Going into Monday's game against Tampa Bay, the Kraken will look to their third line to keep the offense coming.
