The Predators kept coming at the Ducks, though, and Colin Wilson scored to tie it 2-2 when he reached out with one hand on his stick to redirect Ryan Ellis' pass by Gibson on a rush at 7:55.
"I thought the beginning of the second period, after we scored the goal to take a lead, they took it to us pretty good for about 10 minutes," Boudreau said. "Then they got the tip goal, and it sort of changed the momentum all around."
Jamie McGinn nearly gave Anaheim the lead with 2:26 left in the second period, but Ellis dove into the net to make the save.
"I felt it hit me, but I didn't know where it was," Ellis said. "I figured lie down and hopefully it's underneath me. [Rinne] recovered really well and he ended up covering it. I was there as a last measure."
Ellis was an unsung hero for Nashville with those two plays.
"He had a really nice play and really played a real strong game," Predators coach Peter Laviolette said. "The one that he kept out of the net was almost a little bit more fluky than anything else. I'm not sure when he went down in the net that was the plan, but he just found himself there and was able to put up a wall right on the goal line."
Anaheim defenseman Josh Manson left the game with an upper-body injury after he was hit by Forsberg following a shot late the first period. Forsberg was not called for a penalty.
