DENVER (AP) - Brady Quinn leapfrogged Tim Tebow, at least for one night.
Kyle Orton, who has rendered the quarterback drama in Denver a question of who will be his backup, led the Broncos on two touchdown drives in a 24-10 victory over the Buffalo Bills on Saturday night.
Quinn had a mostly solid performance, throwing a touchdown pass but also an interception, and Tebow had a sack and a big scramble in cleanup duty.
The game was marred by an injury to Bills running back Johnny White, who was strapped to a body board and carted off the field after his head was driven into the grass on a clean tackle by linebacker Mario Haggan in the third quarter. White moved his left hand as he was taken up the tunnel, then was taken via ambulance to a hospital. There was no immediate word on his condition.
Haggan later went to the locker room with an injured right shoulder and didn't return.
After Orton completed 10 of 13 passes for 135 yards and a touchdown, Quinn came in and had an up-and-down performance with the second-stringers, completing 10 of 16 passes for 130 yards, one TD and one interception in the end zone just before halftime. Tebow was 1 for 2 for 10 yards with a sack. He ran once for 7 yards.
Orton's sharpness was in stark contrast to his 2-for-6 performance that led to a field goal in the starters' only series last week in an opening lass at Dallas.
Buffalo is 0-2.
Texans 27, Saints 14
HOUSTON (AP) - Arian Foster ran for two touchdowns and Ben Tate rushed for 95 yards and another score in the first half in Houston's victory over New Orleans.
Foster, the NFL's leading rusher in 2010, returned after sitting out Houston's victory in the preseason opener Monday night against the New York Jets because of a sore hamstring.
Tate, a second-round pick in 2010, was seeing his first game action since breaking his ankle in the first preseason game last year. He had a 4-yard TD run and gained 43 yards on another run in the second quarter.
Drew Brees went 7 for 14 for 109 yards in a little more than a quarter for the Saints (1-1). Chase Daniel threw a TD pass to Joseph Morgan, and Mark Ingram scored for New Orleans.
Rams 17, Titans 16
ST. LOUIS (AP) - Sam Bradford threw an 83-yard touchdown pass to Brandon Gibson on St. Louis' first play, and Josh Brown kicked a 42-yard field goal as time expired to give the Rams the victory.
Steven Jackson was limited to 10 yards on six carries in his preseason debut for the Rams (2-0), and Sam Bradford had no other big plays in the first half and got banged around a bit.
Tennessee starter Matt Hasselbeck was sharp, going 7 for 9 for 74 yards. Hasselbeck was shaken up on his final play when Brady Poppinga rolled into his legs after a pass, but after walking off didn't need treatment on the sideline. Rookie Jamie Harper had 83 yards on 11 carries in the first half for Tennessee (1-1). The highlight was a 46-yarder on a cutback run, and he scored for the second straight week.
49ers 17, Raiders 3
SAN FRANCISCO (AP) - Alex Smith threw for 126 yards and an interception in San Francisco coach Jim Harbaugh's home debut, getting showered with a mix of boos and cheers.
Smith was 8 for 13 and came up empty in the end zone again. He had a pass picked off by defensive end Matt Shaugnessy in the second quarter and could only lead the 49ers (1-1) to a field goal in one half of play.
The 2005 No. 1 overall pick at least left healthy. Oakland starting quarterback Jason Campbell didn't return after taking a couple of blows on a scramble play in the second quarter.
The Raiders are 0-2.
