"Jack is a veteran defenseman that we brought into camp to help shore up our depth on the back end," said Avalanche Executive Vice President / General Manager Joe Sakic. "He provides a steady presence and brings a lot of NHL experience to our team. We like what he has added to our blue line over the past few weeks and we're pleased to have him on the club as we head into the start of the season."
Selected by Carolina with the third overall pick in the 2005 NHL Entry Draft, Johnson spent his first five-plus NHL seasons with the Kings after being acquired by Los Angeles on Sept. 29, 2006.

With the Blue Jackets, Johnson finished first among Columbus defensemen in hits (180) and blocks (127) in 2013-14 and was first in blocks (131) in 2014-15. He led the Blue Jackets with seven points (3g/4a) during the 2014 playoffs. The left-shot defender signed as a free agent with Pittsburgh on July 1, 2018 and spent two seasons with the Penguins before joining the Rangers as a free agent on Oct. 9, 2020.
