The Ravens had hoped to play quarterback Joe Flacco and the rest of the first-team offense about a quarter, but very little went according to plan early last night against the Dallas Cowboys.

Less than three minutes into the game, their top healthy corner, Jimmy Smith, was on the sideline, bent over in pain. Flacco didn't take a snap until there was less than four minutes to play in the first quarter and when he did, the Ravens already had 14 points on the board. Running back Ray Rice didn't start and didn't get into the game until early in the second quarter, but his night ended after just two carries when he was taken into the locker room to have his shoulder examined.

Yet by night's end, the Ravens were feeling pretty good about themselves, a 37-30 victory over the Cowboys at AT&TStadium raising their preseason record to 2-0 and revealing enough positives to make up for a slow start for their defense.

X-rays of Smith's chest and Rice's shoulder were negative. Flacco brushed off early inactivity and inaccuracy to lead the Ravens to points on three of the final four drives of the second quarter, including a nifty 19-yard touchdown pass to Torrey Smith. Flacco played the entire first half.

“Happy with the victory,” Ravens coach John Harbaugh said. “Crazy game, really. ... With how the first half went, stats were one way and the points were the other way. That's kind of how it works sometimes. We got a little sloppy in the second half. Our coverage and tackling wasn't very good."

The Ravens built a huge lead against the Cowboys on the strength of touchdowns by their defense and special teams. Strong-side linebacker Courtney Upshaw scooped up a muffed handoff between Dallas quarterback Tony Romo and running back DeMarco Murray and rumbled 26 yards for a touchdown. Wide receiver Deonte Thompson, in a battle to make the team, returned a kickoff 108 yards for a touchdown.
