Erik Haula gave the Predators a 3-1 lead at 10:18 by redirecting a shot from Brady Skjei, and Forsberg made it 4-1 on the power play at 12:37 with a wrist shot from the top of the slot off a pass from Stamkos.
Wood pushed it to 5-1 at 14:44 when he tipped a shot by Roman Josi.
“We’re still there making a playoff push,” Josi said. “You see a lot of guys go (in trades) that meant a lot to this team. We’re a tight group. We’ve been through a lot together, even this year with the way that we started and then came back and we battled. It’s kind of always been about the group and the guys in this room.”
McAvoy pulled Boston within 5-2 at 6:05 of the third period, scoring on a wrist shot from the left circle to the far side.
“I didn’t like our mentality going in,” Boston coach Marco Sturm said. “It’s always tough when the opponent is missing or scratching guys. I’ve seen it a lot of times before. It’s not like we took it lightly, but the guys who came in worked extremely hard and they worked more than us. That was the difference.”
After Arvidsson made it 5-3 at 15:32, Luke Evangelista scored into an empty net at 17:33 for the 6-3 final.
Predators forward Ryan O'Reilly was scratched because of an upper-body injury.
Before the game, Nashville traded forward Michael Bunting to the Dallas Stars for a third-round pick in the 2026 NHL Draft. The Predators traded forwards Michael McCarron (to the Minnesota Wild) and Cole Smith (to the Vegas Golden Knights) on Tuesday, and defenseman Nick Blankenburg (to the Colorado Avalanche) on Wednesday.
Nashville recalled forwards Joakim Kemell, Reid Schaefer and Fedor Svechkov, and defenseman Ryan Ufko from Milwaukee of the American Hockey League on Thursday. Each was in the lineup.
Ufko, playing his second NHL game, got his first career point with the secondary assist on Forsberg’s goal.
“Today we were more prepared, I guess, for what happened,” Predators forward Jonathan Marchessault said. “We were able to play with a lot of energy still.”
NOTES: Bruins defenseman Jonathan Aspirot missed the game because of an illness.
