Yanda, who is dealing with knee and shoulder injuries, and Ngata, who has a knee injury, haven't practiced all week. Traditionally, Ravens who don't practice at all do not play that week.
Ravens defensive coordinator Dean Pees said yesterday that Ngata was "getting some well-deserved rest." However, he said that he was not concerned about the Pro Bowler's availability for Sunday.
Ngata and Yanda have each missed one game this season.
