All the Ravens who were questionable for Sunday's game will be playing.
Ngata has yet to miss any games with his lingering shoulder and knee issues. He did not practice on Wednesday and Thursday, but was limited Friday.
Ngata did tell The Baltimore Sun that the injuries are limiting him, however.
Yanda and Williams didn't practice Wednesday and Thursday and were limited Friday. Yanda hasn't missed a start since 2009.
Having Yanda and Williams both in the lineup maintains Baltimore's starting rotation in the trenches.
The Ravens' other inactives are defensive end
For the Raiders, running backs Darren McFadden and Mike Goodson were already ruled out. Taiwan Jones will get the start and split carries with fullback Marcel Reece.
Oakland's other inactives are tackle Khalif Barnes, offensive lineman Lucas Nix, defensive end Jack Crawford, quarterback Terrelle Pryor and Pro Bowl defensive tackle Richard Seymour, who was also ruled out.
