OWINGS MILLS - Dallas Cowboys running back DeMarco Murray burst through an attempted tackle at the line of scrimmage, exploding into the Ravens' secondary where he stiff-armed safety Ed Reed out of the way before finally being pushed out of bounds after a 28-yard gain.
Fellow Cowboys running back Felix Jones scored on a 22-yard run just two plays later, eluding two Baltimore defenders along the way.
It was the beginning of a long day for the Ravens' rush defense.
Dallas entered the weekend ranked 29th in the NFL - out of 32 teams - in rushing offense (67.8 yards per game), but gashed Baltimore for 227 yards on 42 carries while averaging more than five yards per carry.
The 227 rushing yards were the most allowed by the Ravens in franchise history.
Baltimore has yielded 441 rushing yards in its last two games.
The Kansas City Chiefs racked up 214 yards on 50 carries against the Ravens just a week earlier.
"Our No. 1 priority is going to be stopping the run," Baltimore coach John Harbaugh said. "We have to stop the run. That's something that we take great pride in. Our guys know that. We all feel that way, and we'll go to work on that."
Traditionally stout against the run, the Ravens are ranked 26th in the NFL in rush defense (136.5 yards per game).
They have yielded at least 200 rushing in back-to-back games. Prior to that, only four teams had ever eclipsed 200 rushing yards against Baltimore in the history of its franchise.
"You've got 214 and 227 back-to-back, that's horrible," Ravens safety Bernard Pollard said, later adding, "The missed tackles, they've got to stop. We are a tough football team, we really are... but we just have to be able to go out there and execute."
The Cowboys threw the ball nearly 70 percent of the time in their first four games, but employed a run-first approach against the Ravens Sunday.
Murray had 93 yards on 14 carries despite missing most of the second half with a foot injury, Jones had 92 yards and a score on 18 carries and even third-string ball-carrier Phillip Tanner (nine carries, 31 yards) and fourth-stringer Lance Dunbar (one carry, 11 yards) had some success as well.
"They haven't defended the run as well as they have in the past," Dallas coach Jason Garrett said of Baltimore, later adding, "When you have the opportunity to run the ball, make positive plays and not make the negative plays, play downhill with them, you're going to keep doing it."
Chiefs running back Jamaal Charles rushed for 140 yards against Baltimore a week earlier, 125 of which came during the first half.
We saw on tape after last week in Kansas City that we could attack them there," Cowboys tight end Jason Witten said, later adding, "That was the plan going in, and the guys did a really good job."
And considering the struggles of the last two weeks, Ravens safety Ed Reed expects teams to continue to challenge the Ravens on the ground going forward.
Baltimore will also be forced to cope with the loss of leading tackler Ray Lewis, who will miss the rest of the season with a torn right triceps.
The Ravens travel to face the Houston Texans Sunday.
Texans running back Arian Foster is the NFL's second-leading rusher (561 yards).
"We know teams are going to come in now and try to run," Reed said. "We're conscious of that. We have to make the corrections."
