The Seahawks made some previously reported roster moves official Tuesday and placed Pro Bowl safety Earl Thomas on the season-ending injured-reserve list.

Thomas suffered a broken tibia in last Sunday’s win over the Panthers, and Seahawks coach Pete Carroll said Monday that Thomas wouldn’t be able to return this season.

As previously reported, the Seahawks addressed their depth following the loss of Thomas by signing safety Jeron Johnson. The team also officially announced the signing of fullback Marcel Reece.

Rookie running back George Farmer was waived. Farmer had been called up from the practice squad two weeks ago when the Seahawks were dealing with a bunch of running back injuries. Fellow rookie running back Troymaine Pope returned to action last week.
