NFL: Houston 20, Kansas City 3

HOUSTON, Sept. 9 (UPI) -- Matt Schaub threw for 225 yards and a touchdown in his first game as Houston quarterback Sunday, as the Texans defeated Kansas City, 20-3.

Houston worked a trade with Atlanta to acquire Schaub, who had been the backup quarterback to Michael Vick with the Falcons. The Texans then released David Carr, the only starting signal caller the franchise had ever had.

Schaub completed 16 of 22 passes, seven of those throws going to Andre Johnson for 142 yards.

Mario Williams, Houston's controversial No. 1 draft choice of a year ago, returned a fumble 38 yards for his first NFL touchdown, and he had two sacks. The Texans chose Williams over quarterback Vince Young or running back Reggie Bush in the 2005 draft.

Kansas City quarterback Damon Huard was 22 of 33 for 168 yards and was intercepted twice. Larry Johnson, the NFL's second-leading rusher last year, gained only 43 yards on 10 carries.
