After missing last Sunday's game and sitting out practice Thursday because of a sprained left ankle, linebacker Elvis Dumervil got back to work and is listed as questionable for Monday's game at Detroit.
Dumervil could be crucial to the Ravens, who will be looking to shut down the NFL's second-best offense and third-ranked passing game. Safety Brynden Trawick (ankle) is also questionable while cornerback Lardarius Webb (abs) is probable.
The Lions could be thin in the secondary with cornerbacks Chris Houston (toe) and Darius Slay (knee) both listed as doubtful.
Running back Reggie Bush is questionable after aggravating his calf injury during pregame warmups before last Sunday's loss to the Eagles. Defensive end Ezekiel Ansah (shoulder) is also questionable while five players are listed as probable: Safety Louis Delmas (knee), wideout Calvin Johnson (knee), defensive end Isreal Idonije (knee), tackle LaAdrian Waddle (elbow) and safety John Wendling (illness).
