The Ottawa Senators have signed defenceman Lassi Thomson to a one-year, two-way contract for the 2025-26 season, the team announced Sunday.

The deal carries an average annual value of US$775,000 in the NHL and $300,000 in the American Hockey League.

The six-foot, 192-pound Thomson has appeared in 18 NHL games -- 16 in 2021-22 and two in 2022-23 -- with the Senators.

Thomson was claimed off waivers by the Anaheim Ducks on Oct. 1, 2023, then reclaimed by Ottawa off waivers on Oct. 9, 2023. He has appeared in 202 games with the Belleville Senators, scoring 24 goals and 93 points for Ottawa’s AHL affiliate.
