BALTIMORE (AP) - The Baltimore Ravens received a typically solid performance from their defense in defeating the Cincinnati Bengals 17-10 Sunday.

The Ravens (1-0) forced two turnovers and limited the Bengals (0-1) to 154 yards to make John Harbaugh a winner in his debut as an NFL coach. Cincinnati's Carson Palmer was 10-for-25 for 99 yards, and his interception ended the Bengals' deepest foray into Baltimore territory - except for a 65-yard fumble return for a touchdown by Johnathan Joseph.

Palmer was outplayed by Ravens rookie Joe Flacco, forced into the starting role because of a season-ending shoulder injury to Kyle Boller and Troy Smith's infected tonsils. Flacco ran for a 38-yard touchdown to put Baltimore up 17-3 in the third quarter and deftly operated within the careful attack deployed by Harbaugh and new offensive coordinator Cam Cameron.

Flacco went 15-for-29 for 129 yards and no interceptions.
