The 25-year-old defenseman could have been a restricted free agent July 13. He had seven points (two goals, five assists) in 66 games this season, including one goal in 13 games for the Predators after he was acquired in a trade with the Seattle Kraken on March 20.
"Nashville is the place I wanted to be, so I am thankful and fortunate to stay with this city and the Predators for the next few years," Lauzon said. "As a defenseman who likes to play with physicality, I love the identity our team brings each game and knew this was a group I would fit in with right away. My teammates and the entire organization made me feel welcome from the day I arrived, and I'm looking forward to some stability and a chance to help our team that's on the rise and is heading in the right direction."
Selected by the Boston Bruins in the second round (No. 52) of the 2015 NHL Draft, Lauzon has 18 points (five goals, 13 assists) in 142 regular-season games for the Predators, Kraken and Bruins, and no points in 16 Stanley Cup Playoff games.
"When we acquired Jeremy back in March, we felt he was a player with a bright future who would help solidify our blueline moving forward, so we are excited to have him remain with the Predators," Nashville general manager David Poile said. "Jeremy jumped right into our lineup with his physical style of play and fits the identity that we like to bring each night. At just 25 years old, he's helped us further reach our goal of getting younger and he is thrilled about the opportunity to continue to improve and develop with our organization and in the city of Nashville."
Filip Forsberg, a 27-year-old forward who had NHL career highs in goals (42), assists (42) and points (84) in 69 games, is a pending unrestricted free agent.
The Predators (45-30-7) cliched the second wild card into the playoffs from the Western Conference and were swept by the Colorado Avalanche in the best-of-7 first round.
