Plasek, 23, spent the 2022-23 season in Czechia with Olomouc HC on a loan from the Vancouver Canucks, where he scored 15 points (6 goals, 9 assists) in 31 regular season games. He followed that up with a strong performance in the playoffs by tallying 5 points in 7 games.
Once Plasek clears unconditional waivers on Thursday afternoon, he'll have his contract terminated and will likely be returning to Czechia, potentially to play with Olomouc HC again.
