The Seahawks are setting up their roster for this week’s game against the Cardinals and making a change at defensive tackle is part of the process.

The team announced on Tuesday that they have placed Garrison Smith on injured reserve and signed Sealver Siliga. Smith was listed as questionable with an oblique injury on last week’s injury report, but played against the Falcons.

Smith saw action in three games, making five tackles, with the Seahawks after signing with them in early September. He was with the 49ers over the summer, but didn’t make the 53-man roster.

Siliga signed with the Seahawks in March and was released with an injury settlement after hurting his calf in August. That left him free to sign with other teams, but he couldn’t return to the Seahawks until now. Siliga played 25 games for the Patriots over the last three seasons, including their Super Bowl win over the Seahawks, and had 5.5 sacks.
