Wide receiver Mike Hass has been placed on injured reserve, and offensive lineman Trevor Canfield signed to fill his roster spot.
Coach Jim Mora announced the moves at his just-completed Q&A session.
Hass dislocated a shoulder on the opening kickoff against the Packers in Green Bay on Sunday, after being signed off the practice squad on Saturday.
Canfield (6-5, 307) was signed off the Arizona Cardinals’ practice squad. He was a seventh-round draft choice this year out of Cincinnati.
In other injury news:
Wide receiver Nate Burleson will not play in Sunday’s season finale against the Tennessee Titans at Qwest Field because of the high ankle sprain that also has sidelined him for the past two games.
Linebacker Aaron Curry is doubtful because of the stinger he got two weeks ago in the loss to the Buccaneers.
Running back Julius Jones (ribs, foot) and cornerback Josh Wilson (hip) are questionable and will not practice today, but Mora is not ruling them out for Sunday.
Linebacker Leroy Hill also will not practice after he woke up this morning with a swollen knee. But Mora said Hill should be OK by Sunday.
