Thomson signed a one-year, two-way contract with the Senators to return to North America, the team announced Sunday.
EDGE Analysis
Thomson spent last season in the SHL with Malmo, scoring 17 goals and adding 12 assists in 50 games, but he's on his way back to North America. The 24-year-old has played 18 games in the NHL with five assists to his name, but none since the 2022-23 season. The 2019 first-round pick will look to crack a crowded Senators blue line with six other players already under contract.

Thomson has signed a contract with with the Malmo Redhawks of the SHL.
EDGE Analysis
Thomson wasn't able to catch on with the Senators after being selected by the team with the 19th overall pick in the 2019 Draft -- he appeared in 18 games with Ottawa from 2021-23, picking up five helpers and a minus-10 rating over that span, but he didn't see any action with the big club in 2023-24, instead spending the entirety of the campaign with AHL Belleville, recording 21 points in 67 contests. As a restricted free agent, the Senators still own Thomson's NHL rights, so they'll get the first crack at signing him if he returns to North America in the future.
