The 2013 season was the Baltimore Ravens' 18th in the National Football League (NFL) and their sixth under head coach John Harbaugh.

For the first time in franchise history, Ray Lewis was not on the roster, as he announced his retirement before the playoffs began the year prior.

The Ravens drew first blood when Joe Flacco found Vonta Leach on a 2-yard touchdown pass to take the lead 7–0 in the first quarter for the only score of the period.

The Ravens tried to rally a comeback in the last quarter, with Flacco finding Marlon Brown on a 13-yard pass to shorten the Broncos' lead 42–24 followed up by Tucker's 30-yard field goal to make the score 42–27.

However, the Broncos wrapped things up in the game when Peyton found D. Thomas again on a 78-yard pass to make the final score 49–27.

The Ravens began their season 0–1 for the first time under John Harbaugh as head coach and Joe Flacco as their starter.

With the win, the Ravens avenged their 30-point blowout last year to Houston, improved to 2–1 overall and 7–1 all time against the Texans, including playoffs.

At the end of the fourth quarter, Andy Dalton threw a 51-yard Hail Mary that was first tipped by Ravens defender James Ihedigbo at the goal line, but eventually found A. J.

However, about five minutes into overtime, Justin Tucker kicked the winning field goal (46 yards), and the Ravens improved to 4–5.

Controversy erupted in the third quarter when Steelers' head coach Mike Tomlin stood on the field along his team's sideline as Jacoby Jones broke free on a kickoff return for a potential game breaking touchdown.

[2] Tomlin, with his back to the approaching play, appeared to glance over his shoulder then place his foot briefly onto the field as he jumped out of the way, causing Jones to veer inside where he was tackled.

Marlon Brown caught a nine-yard pass from Joe Flacco with four seconds remaining, and the Ravens improved to 7–6.

With the loss, the Ravens fell to 8–7 and back to seventh place in the playoff hunt, enabling their division rivals Bengals to secure the AFC North title.

With this defeat, the Ravens were eliminated from post-season contention, assuring the NFL of a new Super Bowl Champion for the ninth straight year.
