CINCINNATI (AP) Andy Dalton and the rest of the Bengals' offense were so good that they got the night off after less than 3 minutes.

Dalton completed all of his three passes, and the Bengals' starting offense was impressive in its only drive Friday night during Cincinnati's preseason 23-10 victory over the New York Giants.

Dalton was 3 for 3 for 31 yards, including a 3-yard touchdown pass to Mohamed Sanu. Coach Marvin Lewis decided that was enough, resting his starting offense after only 2 minutes, 55 seconds on the field. Dalton had completions of 12, 16 and 3 yards, and Jeremy Hill ran twice for 15 yards.

''I think what everybody saw just shows that we came out fully prepared,'' Dalton said. ''It's not that much but sure, it's a good start to the season. The first-unit guys were glad we could earn ourselves a short night.''

It was much different for the Giants' starters. Eli Manning and the rest of the offense stayed on the field until early in the second quarter, managing only one first down and 38 yards in four series.

''We need to be a little sharper,'' said Manning, who was 4 of 8 for 22 yards. ''We definitely have room for improvement. That's what preseason's for, to figure out what you have to improve on and go do it.''

The Giants lost two rookie safeties from their reconfigured secondary. Second-round pick Landon Collins left in the first injury with a knee injury - X-rays were negative - and fifth-rounder Mykkele Thompson hurt his right Achilles tendon while covering a punt and was taken off the field on a cart.

The teams practiced against each other for two days last week without incident. The two combined practices gave the Bengals an idea of what to expect.

''Really, we just played against what we saw in practice against them this week,'' defensive end Carlos Dunlap said. ''We were fortunate that they gave us some plays we were ready for. You can't read a lot into this; it's just one quarter of a preseason game. But I see it as the first building block to getting where we want to be.''
