Seattle signed Thompson to a reserve/future contract Monday, Aaron Wilson of KPRC 2 Houston reports.
Thompson earned a practice-squad contract after failing to make the Seahawks' initial 53-man roster, but he didn't make any appearances during the 2022 campaign. The Utah State product impressed during limited preseason action, and with his new contract, he'll have a chance to build off what he did with Seattle this year throughout the upcoming offseason.
