From 2023-2025 as a member of the San Jose Sharks, Fabian Zetterlund showed the potential he had when he recorded 83 points with 41 of them being goals. Zetterlund's excellent play on a bad team helped teams draw interest in him at the 2025 trade deadline
Just before the 2025 trade deadline ended, the Ottawa Senators traded for Zetterlund. Although he struggled with recording five points in 20 games after the trade, the Senators re-signed Zetterlund to a three-year contract this offseason.
This season, high expectations were on Zetterlund with a full season ahead of him in Ottawa at 26 years old.
