MacLean was put on non-roster waivers by the Islanders on Saturday.
MacLean has no points, 17 PIM and 21 hits in eight appearances in 2026-27. Putting him on non-roster waivers, as opposed to the regular version, means he's been taken off the NHL roster even before he officially clears. Mathew Barzal (knee) was activated off injured reserve in a corresponding move, which is why the Islanders wanted to create a roster opening immediately.
