Kris Draper added an empty-netter with 13 seconds left for league-best Detroit, which won its sixth in a row.
Peter Budaj stopped 34 shots for Colorado.
An apparent goal by the Avalanche's Milan Hejduk with 8 seconds left in the second period was waved off because of incidental contact with Hasek.
Colorado didn't have a shot until T.J. Hensick forced Hasek to make a save 11:20 into the game.
Detroit had a 14-3 shot advantage in first period. The Avalanche had only one shot in the second period and it didn't come until 9:28. Detroit had nine shots in the second period.
RANGERS 2, DEVILS 1
In Newark, N.J., Chris Drury scored two goals and Henrik Lundqvist made 33 saves as New York continued its dominance of New Jersey.
The Rangers have won all five meetings this season and Lundqvist has been a major part of that success. He was in net for all five wins, allowing only five goals.
Brandon Dubinsky also scored the Rangers who have won two in a row -- on the road on consecutive nights.
Zach Parise scored for the Devils who have only two wins in their last seven games with all five loses coming on home ice.
PREDATORS: Forward J.P. Dumont signed a four-year, $16 million contract with Nashville on Friday.
Dumont, in his second season with the Predators, ranks second on the team in goals (18), assists (27) and points (45). He currently has a franchise record 16-game point streak dating to Dec. 29.
In the past seven seasons, he has 160 goals and 207 assists in 568 games with Chicago, Buffalo and Nashville.
Dumont had a club-record six-game goal streak this season. The 29-year-old right winger came to the Predators as an unrestricted free agent prior to last season. He's currently an alternate captain.
David Poile, the Predators' president/general manager, cited Dumont's "commitment, leadership, work ethic and reputation as a big-game performer."
"When he expressed a desire to stay in Nashville, we jumped at the opportunity to keep him as part of our team's foundation for the next four seasons," Poile said.
