Kraken's Jacob Melanson Sidelined Long-Term After Serious Chest Injury

Seattle announced that forward Jacob Melanson will be out indefinitely after he was diagnosed with an anterior mediastinum hematoma and vascular pseudo aneurysm. The injury occurred during the team's Oct. 1 season opener at Calgary, and the club said he will be monitored closely as he progresses toward a return. Melanson, 23, had five points in 36 games last season and had been listed as week-to-week before the updated diagnosis.
Seattle disclosed that Jacob Melanson will be sidelined with no set return date. The 23-year-old forward was diagnosed with an anterior mediastinum hematoma and a vascular pseudo aneurysm after appearing in the Oct. 1 opener at Calgary. He logged 9:31, recorded one shot, and exited the game.
The Kraken had initially labeled him week-to-week. Last season, Melanson posted five points and 32 penalty minutes across 36 appearances. Seattle drafted him in 2021's fifth round, No. 131 overall, and he has five points in 38 NHL games. The team plans close monitoring and a gradual return.
Melanson’s indefinite absence could affect the Kraken’s forward depth and physical presence, while teammates and fans may feel concern for a young player facing an unusual diagnosis. The case may also draw attention to chest trauma in hockey and the importance of cautious medical follow-up. For Melanson, the uncertainty could shape his near-term career trajectory and return timeline, though the team’s stated monitoring plan may support a gradual recovery.
