Cardwell has been put on waivers by San Jose on Wednesday.
Cardwell had seven goals, 15 points and 17 PIM in 24 regular-season appearances with AHL San Jose in 2025-26. He also had a goal in seven regular-season appearances with the Sharks last campaign. Cardwell is expected to start the upcoming campaign in the minors, but he will likely get some work in the NHL in 2026-27.
