BALTIMORE -- Jaguars quarterback Blake Bortles stayed on his feet even as Baltimore Ravens linebacker Elvis Dumervil stormed through the line of scrimmage for apparent game-ending sack.

That proved to be a vital decision as Dumervil was flagged for grabbing Bortles' facemask as he slung him to the ground. That penalty moved the ball from the Ravens' 49-yard line to the 35 and gave Jacksonville one final untimed play.

From there, Jason Myers calmly booted a 53-yard field goal that gave Jacksonville an improbable 22-20 victory over the struggling Ravens on Sunday.

"I was just out there trying to do something to get us downfield," Bortles said. "That was probably the wildest finish I've ever been involved in."

Jacksonville (3-6) snapped a 13-game losing streak on the road and improved to 3-6. The Ravens (2-7) lost for just the second time in eight games following a bye week under coach John Harbaugh.

"Obviously, just about as tough as a loss as you're ever going to see," Harbaugh said. "Really, what we have to deal with right now is how we handle it, where we go forward from here."

Baltimore quarterback Joe Flacco had three straight turnovers in the second half that killed potential scoring drives. He completed 34 of 45 passes for 316 yards with three touchdowns, two interceptions and a lost fumble.

The Ravens' defense sacked Bortles four times and got its first turnover since Week 3 on an interception by cornerback Lardarius Webb.

Nonetheless, the Jaguars found a way to win.

"Unbelievable game," Jacksonville coach Gus Bradley said. "Give credit to both teams with that game going back and forth. We knew it was going to be a one possession game just by the history of both teams."

Flacco threw a pair of interceptions to cornerback Davon House and also lost a fumble in the third quarter. The Jaguars, however could only manage a 45-yard field goal by Jason Myers that pulled them to within 14-10.

Jacksonville got another break when cornerback Nick Marshall recovered a fumble by the Ravens' punt returner Jeremy Ross at his own 37. A personal foul on Baltimore safety Will Hill provided Jacksonville with another 15 yards. This time, Bortles made them pay with a 15-yard touchdown pass to wide receiver Allen Robinson for a 19-14 lead with 13:01 left in the game.

Flacco recovered and threw a 14-yard touchdown pass to wide receiver Chris Givens on the next possession for a 20-19 Ravens lead when the two-point conversion failed.

"At the end of the day, we're just not good enough," Flacco said. "It shows on your record."

Jacksonville then used its two-minute offense to get the ball to midfield. Ravens safety Kendrick Lewis had let an easy interception slip through his hands on the final drive.

"Absolutely, I had a chance to seal it," Lewis said. "No matter what happens in the game, I had an opportunity and didn't respond."

That proved costly as Dumervil committed the crucial penalty, setting up Myers' game-winning kick.

"I was ready for it," Myers said. "Once we got the ball back, I spent my time concentrating and preparing for a chance I hoped would come."

Bortles completed 22 of 45 passes for 188 yards with two touchdowns and an interception.

The Jaguars took a 7-0 lead on a 5-yard pass from Bortles to wide receiver Allen Hurns, who became the first player with a touchdown catch in seven straight games since the Cowboys' Dez Bryant in 2012.

Baltimore forced its first turnover in five games when Webb intercepted Bortles. Two plays later, Flacco tied the game with 10-yard pass to tight end Crockett Gillmore with 11:32 left in the second quarter.

A pass interference call on Ravens cornerback Jimmy Smith gave the Jaguars the ball on Baltimore's 14. Jacksonville, however, had to settle for a 21-yard field goal by Myers.

The Ravens responded on the ensuing possession when tight end Maxx Williams caught his first career touchdown on a 21-yard pass from Flacco that provided a 14-10 lead at the break.
