Vatanen agreed to terms on a one-year contract with Swiss club Geneve-Servette on Monday.
Vatanen split last season between New Jersey and Dallas after being claimed off waivers by the Stars in April. In total, the 30-year-old blueliner appeared in 39 games in which he tallied just six points. Given his limited offensive upside, few fantasy players should be impacted by his move away from the NHL.
