In a post on social media, Antonietti states that he will no longer be part of Genève-Servette HC. The 27-year-old has spent his whole career so far under contract with Geneva. Recently, he was also suiting up on loan for the SC Rapperswil-Jona Lakers and HC Ajoie.
This season, the defender only made five games, all for the Lakers, due to injury-related reasons. He has not suited up since the end of October.
