The 27-year-old Blankenburg, who has recorded 21 points (6 goals, 15 assists) in 49 games this season, will likely serve as the Avalanche's seventh defenseman. Standing at 5-foot-9 and 177 lbs, he's an unrestricted free agent this summer on an expiring $775K contract.
Colorado continues to bolster their defensive core less than 48 hours before the NHL Trade Deadline, though the team still needs to address their forward group. The Predators receive a 2027 5th-round pick for the depth defenseman.
