It is indeed a very unique and rare way to announce the end of an association between a team and a player.

Here is their statement:

“The Trois-Rivières Lions have placed forward William Lemay on the suspended players’ list in order to remove him from the lineup.

Good luck in the future, William!”

– Trois-Rivières Lions

So, William is suspended by the team for contract termination purposes, but they wish him good luck in his future endeavors.
