Oliver Kylington signed a one-year contract with the Colorado Avalanche on Monday. Financial terms were not disclosed.

The 27-year-old defenseman had eight points (three goals, five assists) in 33 games for the Calgary Flames last season.

He returned to the NHL on January 25 after sitting out the 2022–23 season to care for his mental health. He was a finalist for the Masterton Trophy, given annually to the NHL player who best exemplifies the qualities of perseverance, sportsmanship and dedication to hockey, as voted on by members of the Professional Hockey Writers Association. Arizona Coyotes goaltender Connor Ingram won the award.

Selected by Calgary in the second round (No. 60) of the 2015 NHL Draft, Kylington produced 55 points (17 goals, 38 assists) in 201 regular season games and three points (one goal, two assists) in 12 Stanley Cup Playoff games.
