NFL: Ravens defeat 49ers 23-3 in preseason opener

Joe Flacco needed just one drive to show how effective the Baltimore Ravens’ offense can be under Gary Kubiak.

Flacco produced an 80-yard touchdown march in his only series, and the Ravens beat San Francisco 23-3 in a preseason opener at Baltimore.

It was the third time in three tries that Ravens coach John Harbaugh got the best of his brother, Jim Harbaugh, coach of the 49ers. Baltimore previously defeated San Francisco on Thanksgiving 2011 and in the Super Bowl ending the 2012 season.

After Colin Kaepernick moved the 49ers 66 yards for a field goal, Flacco made himself right at home in Kubiak’s offense, going 4 for 5 for 52 yards.

Redskins 23, Patriots 6: Tom Brady took the night off, and Robert Griffin III played one series Thursday night as the Washington Redskins beat the New England Patriots at Landover, Maryland.

Griffin completed 2 of 4 passes for 9 yards in an 11-play drive that ended with a 39-yard field goal from Kai Forbath.

Patriots coach Bill Belichick rested Brady, Darrelle Revis and most of his starters.

Jets 13, Colts 10: Michael Vick led New York on a touchdown drive, capped by fellow newcomer Chris Johnson’s 1-yard scoring run, in a victory over Indianapolis at East Rutherford, New Jersey.

Geno Smith, looking to retain his starting job in his second season, was 4 of 6 for 33 yards in two series with the first-team offense that included a 51-yard field goal by Nick Folk before giving way to Vick. The 34-year-old backup received a hearty cheer from the crowd at MetLife Stadium, and moved the starting offense for the Jets down the field.

Chiefs 41, Bengals 39: Sean Smith and Malcolm Bronson returned interceptions for touchdowns, De’Anthony Thomas brought back a punt 80 yards for another score and Kansas City defeated Cincinnati at Kansas City, Missouri.

Andy Dalton was sharp in his only series for the Bengals after signing a new six-year deal this week. He hit wide receiver A.J. Green for a 53-yard pass to set up the opening field goal.

Chargers 27, Cowboys 7: New backup quarterback Kellen Clemens threw a 70-yard touchdown pass to Dontrelle Inman midway through the third quarter and San Diego defeated visiting Dallas.
