Groshev was placed on waivers by the Lightning on Sunday.
Groshev signed a two-year, two-way deal with the Lightning in the offseason after another solid year in the organization. He made his NHL debut during the 2025-26 campaign, where he recorded an assist across just two regular-season outings. The 24-year-old winger is headed into his fourth season with AHL Syracuse, where he will continue his development in hopes of being a depth winger for the team in the near future.
