Ravens quarterback Joe Flacco won't look for a return trip to London any time soon.

Flacco posted the worst statistical performance of his career in the Ravens' 44-7 loss to the Jacksonville Jaguars in Wembley Stadium Sunday afternoon.

Things went so poorly that Head Coach John Harbaugh pulled his starter at the beginning of the fourth quarter with the Ravens trailing by 44 points. There was no need for him to go on.

Flacco threw for a career-low 28 yards. He completed just eight passes, which is the fewest he's ever had in a regular-season game in which he was slated to play the entire way.

He threw two interceptions, zero touchdowns and posted a career-low 12.0 quarterback rating.

It wasn't just Flacco who had a rough go of it.

"We couldn't complete a pass, we couldn't get chunks and we couldn't get first downs," Flacco said.

"We all traded turns making our bad plays and that leads to big losses and bad football. … You can't put your finger on one specific thing, but when you go back and watch the tape, there were a bunch of things that weren't good on our front."

The entire offense struggled mightily against a talent-rich Jaguars defense.

Baltimore posted just 186 net yards after averaging 302 over its first two games. The Ravens got just 12 first downs – half as many as the Jags – and avoided a shutout with a touchdown in the last few minutes.

Wide receivers had passes bounce off their hands and didn't make any plays down the field. Mike Wallace caught one pass for 6 yards and Jeremy Maclin caught one for 8 yards and spent part of the game in the concussion protocol.

"They had a good game plan," Maclin said, adding that the Jaguars took away the middle of the field. "It's our job to adjust and today we didn't do that."

Baltimore's running game, which had been the engine of the offense in the previous two wins, grinded to a halt until late in the game. Terrance West rushed six times for 26 yards and lost a fumble that was nearly returned for a touchdown. Javorius Allen ran eight times for 15 yards.

Alex Collins sparked the Ravens' only touchdown of the game with nine carries for 82 yards, capped by a 6-yard touchdown pass from Ryan Mallett to tight end Benjamin Watson.

"Nothing went according to plan," Watson said. "I'll give their defense credit. They pretty much imposed their will."

The biggest difference with the offense was that it was missing six-time Pro Bowl guard Marshal Yanda, who went on injured reserve last week with an ankle injury.

Tony Bergstrom, who came in for Yanda last week, was inactive. Matt Skura started and rotated with rookie London native and fifth-round pick Jermaine Eluemunor. Flacco was only sacked twice, but was often on the run.

"The line was fine," Allen said. "We just have to execute the plays, myself included."
