Franzen then added a short-handed goal and his redirection of Lidstrom’s shot made it 7-1.

After Mikael Samuelsson’s first of two goals gave Detroit a 1-0 lead, the Avs tied it on their very first shot when Joe Sakic assisted Tyler Arnason, who sent the puck over Chris Osgood’s right shoulder.

Osgood stopped the next 22 shots he faced before John-Michael Liles put one past him during a 5-on-3 advantage.

“I won’t apologize for beating them like this,” Zetterberg said. “I know they’ll came back at us next year.”

But with whom?

Sakic, who missed 38 games at age 38 with a hernia this season, has said he’ll wait until the summer to decide if he’ll return for a 20th NHL season.

Forsberg, 34, said after the game that an MRI on Wednesday revealed tears in both groins. He ended up playing 16 games, including seven in the playoffs, after rejoining the Avs at the trade deadline with the understanding he’d play when his chronically bad ankle allowed.

Forsberg said he wants to return to Colorado next season — health permitting. Otherwise, retirement beckons.

“Just too many injuries,” Forsberg said. “If it doesn’t get solved, that would be it, but we’ll see what happens.”

Notes: The Red Wings also swept the season series from Colorado and finished 8-0 vs. the Avalanche. ... Sakic’s two assists gave him 188 career postseason points, tying Doug Gilmour for seventh place all-time.
