That gave the Red Wings a 4-3 lead with one minute remaining in regulation, before they completed a 5-3 victory over the Avalanche on Saturday. Darren Helm scored into the empty net, capping off a four-goal third period for the visitors from Detroit.

The win gives the Red Wings 73 points. They remain in the top Wild Card spot in the Eastern Conference, but move three points clear of Pittsburgh and six ahead of Philadelphia and New Jersey.
Colorado still holds the final Wild Card spot in the West.
Both teams got off to an entertaining start in the first period, with Detroit opening the scoring before Nathan MacKinnon — on a perfect wrist shot for his 20th of the season — and Tyson Barrie scored for the Avs to give them the lead.
After a sluggish second period for both teams, the Red Wings struck for four in the third.
But just over five minutes later, Richards scored what proved to be the winner from a difficult angle.
