1. Carson Palmer continues his hot streak against the Ravens. Palmer is 7-3 against them, delivering two last-minute comebacks. His latest came last month, when he drove 80 yards on 11 plays, capping the rally with a 20-yard touchdown pass to Andre Caldwell with 22 seconds remaining.

2. The Ravens hurt themselves with penalties. They committed a season- worst 10 penalties the last game against Cincinnati. Three of them came in the Bengals' winning drive.

3. Another slow start offensively. In their past three games, the Ravens have scored a total of three points in the first quarter. In their last game, the Bengals took a 14-0 first-quarter lead over Chicago.
