Schaub finished 17-of-30 passing for 290 yards to help Houston move to 3-0 for the first time in franchise history.
Six days after throwing three interceptions in the first quarter of a loss to Atlanta, Manning didn't throw any against the Texans. But just as happened last week, the Broncos fell behind by 20 points and lost by six. Manning did get the ball with 20 seconds left this time but didn't move the Broncos close to the end zone.
The Texans improved to 3-16 lifetime against Manning and beat him for the first time in a road game.
