Kapanen posted six goals and 16 assists across 73 games during the 2023-24 campaign.
The Blues claimed Kapanen off waivers during 2022-23. He immediately showed promise with eight goals and 14 points through the final 23 games last year, but his game never took off this season. The 27-year-old will be a free agent this summer, and it's unclear if he's in the plans moving forward for the rebuilding Blues.
