Flacco (knee) and Rice (thigh) were listed as questionable on the injury report and were limited in Friday's practice.
This marks Flacco's 95th straight regular-season start, the third-longest current streak in the NFL behind Eli Manning (150) and Philip Rivers (128). Flacco, who reportedly sprained the MCL in his left knee, will wear a brace for the game.
Also, outside linebacker Elvis Dumervil is active after being added to the injury report Friday with an ankle injury. He leads the Ravens with 9.5 sacks.
