After managing just three points through 3 1/2 quarters, the Ravens have finally scored a touchdown in San Diego with 4:19 remaining.
That cut the Chargers' lead to 13-10 and means the next four minutes will be nail-biters.
The Baltimore defense is having a second straight stellar game, limiting San Diego to 233 yards and sacking Phillip Rivers six times so far.
Let's see if that effort produces a victory on the road.
Update: The Chargers went three-and-out on the possession following the Ravens' touchdown and then things went haywire.
Jacoby Jones returned the ensuing punt to the Baltimore 40, setting up good field position. In part because of a Marshal Yanda holding penalty and in part because of a Flacco fumble, Baltimore was pushed to fourth-and-29 from its own territory.
And then came the miracle. Flacco connected with Ray Rice for a short dump-off, and the little tailback scampered 29 yards with the help of a stiff arm, a broken tackle and an Anquan Boldin block.
The play was ruled a first down, but a lengthy review followed. The officials pushed the ball back a half-yard, but the Ravens had still moved the chains with 1:40 on the clock.
That allowed Baltimore to come up with the game-tying Justin Tucker field goal as time expired, a 38-yard kick that sends this one to overtime tied at 13-13.
Update II: The Ravens and Chargers went back and forth throughout overtime, and took it to the final minutes before Baltimore came away with a 16-13 victory that improves its record to 9-2.
The Chargers started overtime with the ball, but the Ravens forced them to punt.
Then Baltimore made a push from its own 11 to near midfield, but fizzled there and had to punt away.
The Chargers punted again on their next possession, a 63-yarder, and the Ravens started at their own 11 with 4:56 to go.
The Ravens wouldn't punt again. They drove 69 yards in 12 plays and won on a 38-yard field goal by Tucker with 1:07 remaining.
The big play came on third-and-10 from the Chargers' 47, where Flacco found Torrey Smith for a 31-yard game to the Chargers' 16. The play was reviewed, but Smith clearly caught it and the ruling was upheld as a successful reception.
Flacco then kneeled in the middle of the field to set Tucker up for a straightaway look at a field goal, and then followed with two more kneels to use up the Chargers' timeouts and leave as little time left on the clock as possible.
The delay didn't faze Tucker, who drilled the 38-yarder and gave the Ravens a comeback victory.
