Detroit Lions defensive end Willie Young, right, grabs Cincinnati Bengals quarterback Jordan Palmer (5) in the second half of an NFL preseason football game in Detroit, Friday, Aug. 12, 2011. Palmer threw an interception on the play.

DETROIT — Detroit's defense lived up to expectations when it finally took the field in the Lions' first preseason game.

Detroit intercepted rookie Andy Dalton on Cincinnati's first offensive play and shut down the Bengals in a 34-3 victory Friday night.

The Lions said it was the fewest points allowed by Detroit in the preseason since a 16-0 win over Cincinnati in 1999.

As usual, Ndamukong Suh's presence was felt the most. The second-year defensive tackle knocked Dalton over on Cincinnati's first offensive snap — just after the quarterback released a long pass up the right sideline. The ball was underthrown and intercepted by Chris Houston.
