BALTIMORE, MD (WHBL) - A strong running game and a tight defense allowed Green Bay to win at Baltimore 19-17 on Sunday even though the Packers had just two healthy wide receivers for the entire second half. A pair of key injuries overshadowed Green Bay's first road win of the year, as the defending Super Bowl champion Ravens lost for just the fourth time in their last 30 home contests. Packers' receiver James Jones left early with an injured shin. Randall Cobb left in the second quarter after being chopped just below his right knee by Ravens' rookie safety Matt Elam. There was no word on anything broken for either Jones or Cobb. Coach Mike McCarthy said neither injury appeared to be season-ending, and he hopes to learn more today. Linebacker Nick Perry sprained an ankle on a sack in the first half, but returned for five plays in the second half. Green Bay had 140 rushing yards to just 47 for Baltimore's strong running attack. Rookie Eddie Lacy ran for 120 yards. It was his first career 100-yard game and the fourth for Green Bay in its last five, after going 44 straight games without a 100-yard rusher. It helped the Packers out-gain the Ravens 438-to-360. Aaron Rodgers threw for 315 yards, a touchdown, and an interception. Jordy Nelson caught the Pack's only T-D, a 64-yarder. Nelson had four catches on the day for 113 yards. On defense, McCarthy made a gutsy call in the first half when he declined a 10-yard holding penalty by the Ravens on third down close to the Green Bay goal line, and the Packer defense held on fourth down. Mason Crosby missed his first field goal attempt of the season, but made four more from 50, 45, 31, and 31 yards out. Joe Flacco threw for 342 yards for Baltimore. Tandon Doss had four catches for 99 yards.For the second straight week, the Packers led 6-nothing at the half. Nelson's touchdown late in the third quarter put Green Bay up 16-3. Flacco threw two fourth-quarter touchdowns to Jacoby Jones and Dallas Clark. The Packers held on for the final two-plus minutes to become the first N-F-C team to win at Baltimore in 11 tries. The Ravens dropped to 3and-3. The Packers are 3-2. They'll host Cleveland next Sunday.
