Quarterback Matt Schaub is active for the Ravens Sunday after missing last week with a chest injury, though it's still unclear if he or Jimmy Clausen will start.
However, if their workload in pregame warmups are any indication, Clausen getting the bulk of the throws means he'll likely start for a second straight week.
Schaub returned to practice this week after sitting out all of last week with a chest injury suffered in a 15-13 loss to the Miami Dolphins on Dec. 6, and Clausen threw for a career-high 274 yards in a loss to the Seattle Seahawks a week ago.
Coach John Harbaugh said all week that Schaub was still sore, but would start if he was near 100 percent and gave the team the best chance to win. Quarterback Ryan Mallett, who was signed on Tuesday, is inactive.
Guard Marshal Yanda, who missed two practices this week with an ankle injury, is active after testing his ankle early in pregame warmups.
Tight end Crockett Gillmore is inactive for the second straight game with a back injury that Harbaugh said could land him on injured reserve. Wide receiver Marlon Brown is out for a fourth straight game due to a back injury, while cornerback Kyle Arrington (back) and outside linebacker Albert McClellan (ankle) are also inactive.
McClellan sitting means there are just three healthy outside linebackers — Elvis Dumervil, Courtney Upshaw, and Za'Darius Smith.
Tight end Richard Gordon is also inactive, leaving only Maxx Williams and Konrad Reuland at that position.
Running back Terrance West is active after missing Friday with a calf injury, while cornerback Jumal Rolle will make his Ravens debut. Rookie defensive tackle Carl Davis is active for the first time in three games.
