The Avs ended the first period with a 1-0 lead after Matt Duchene potted a power-play goal with only 1.6 seconds left on the clock.
As part of the deal, Turris will sign a six-year, $36 million extension with the Predators. He scored a career-high 27 goals last season. The Avs traded Duchene in the middle of a game, which is something that hasn't happened in the league in about five years.
The Avalanche receive defenseman Samuel Girard, forward Vladislav Kamenev, and a second-round pick from Nashville, and forward Shane Bowers, goaltender Andrew Hammond, a first-round pick, and a third-round pick from Ottawa.
By the beginning of the 2017-18 season, it had become widely believed that Avalanche GM Joe Sakic would finally pull the trigger on the deal soon. "We've said all along that we wanted to be patient and wait for the right deal, and this is the opportunity we feel is best for the organization".
Duchene is coming off a disappointing season on a team where just about every player struggled.
Matt Duchene has been traded.
The Avalanche play the New York Islanders on Sunday at 4:00 PM, a quick turnaround that will then see the Avs fly all the way to Sweden for a pair with the Ottawa Senators on Friday and Saturday.
"Being pulled in a game, then to be playing my first two games against my old team, is going to be pretty odd", Duchene said.
Kamenev, 21, was a second-round selection (42nd overall) of the Predators in the 2014 NHL Draft and has spent the previous two campaigns with the Milwaukee Admirals. Girard, 19, was a 2016 second round pick of the Predators and made his National Hockey League debut this season. The third overall pick in 2009 has 178 goals and 250 assists in 586 games.
