Jonathan Bernier made 32 saves for the defending Stanley Cup champions, who tied it with 9:34 left on Jeff Carter's goal during a two-man advantage. King then made a spinning pass from the boards in front to Kopitar, who beat Jimmy Howard for his sixth goal of the season.
Howard stopped 27 shots for the Red Wings, who had won two straight after an 0-3-2 skid.
Kyle Quincey scored his first goal of the season on a misplay by Bernier in the first period.
I've never seen anything like that. The great thing is I don't know how many times guys bailed me out where they had to score to keep it alive and they did every time. It was amazing. It's not the way we draw it up, to go 20 rounds here, but obviously it's a big win.
