Walsh signed a contract with the Seahawks on Thursday, Field Yates of ESPN reports.
Walsh struggled mightily in 2016, missing four extra points and making 12 of 16 field-goal attempts prior to being released in November. Steven Hauschka, the Seahawks' kicker in 2016, will be a free agent upon the end of the league year, meaning Walsh could be set to handle the kicking duties in Seattle in 2017.
