The second practice report of Week 12 is out and four players returned to full participation for the Seahawks.

Running back Thomas Rawls (knee), who was limited Wednesday, practiced in full on Thursday, as did wide receiver Doug Baldwin (ankle), right guard J.R. Sweezy (shoulder), and right tackle Garry Gilliam, all three of whom sat out of practice on Wednesday. Center Patrick Lewis (ankle) was also a full participant for the second straight day.

Still not participating in practice for the Seahawks are linebacker Bruce Irvin (knee) and wide receiver Paul Richardson (hamstring), who Seattle head coach Pete Carroll said would be gameday decisions "at best" after missing the team's Week 11 win to injury. Outside of Irvin, Richardson, and running back Marshawn Lynch, who has already been ruled out, the only Seahawks player who sat out Thursday's practice was defensive end Michael Bennett (not injury related), who's typically given a rest day at this point in the practice week. 

For the Pittsburgh Steelers, Seattle's opponent this Sunday at CenturyLink Field, linebacker Ryan Shazier was added to the practice report with a knee injury. He did not participate in practice on Thursday.
