After a scoreless first period, the Predators believed they took a 1-0 lead late into the second when Forsberg found the back of the net, but the Wings challenged that Nashville center Mikael Granlund interfered with Bernier's skate, and after a lengthy official review, the goal was disallowed.
The challenge kept the game scoreless going into the third period, making it just the third time in 102 all-time regular season matchups between Detroit and Nashville that the two clubs went scoreless into the third.
The Predators peppered Bernier with several shots the first few minutes of the third, but the Wings' goalie was up to the task, keeping the game at 0-0 for the time being.
But Red Wings forward Vladislav Namestnikov was called for holding at 4:19 of the third, giving the Predators their third power play of the game, and Nashville immediately took advantage.
Seventeen seconds into the power play, Forsberg took a shot from the point that went off Wings defenseman Marc Staal's stick, floated into the air and over Bernier's shoulder, giving the Predators a 1-0 lead 4:36 into the third.
Forsberg was credited with the goal, earning his team-leading ninth goal of the season. The Predators' alternate captain has registered a point in his each of his last six games against Detroit.
Nearly five minutes later, Wings defenseman Patrik Nemeth was called for hooking at 9:02, and Nashville struck again on the man advantage as Tolvanen scored his third career NHL goal on a well-executed passing play that Bernier had little chance to stop, giving the Predators a 2-0 lead.
