Steven Hauschka kicked a 45-yard field goal in overtime to give the Seahawks a 23-20 win over the Texans on Sunday and the first 4-0 start in franchise history.
Houston (2-2) failed to score on two possessions in overtime. The Seahawks got the win on their second drive in overtime after rallying from a 20-3 deficit.
A key play on the winning drive came when Doug Baldwin caught a 7-yard pass and Kareem Jackson was penalized for unnecessary roughness for dumping him into the ground. That got Seattle in field goal range and Hauschka's kick came four plays later.
The Seahawks rallied to tie it at 20-20 on an interception return for a touchdown by Richard Sherman in the fourth quarter.
Vikings 34, Steelers 27: Greg Jennings made two touchdown catches, Adrian Peterson ran for two scores and the Vikings' defense made a big stop with time running out to preserve a win over the Steelers. Playing at Wembley Stadium, Everson Griffen stripped Ben Roethlisberger on the 6-yard line with 19 seconds left. Kevin Williams recovered to seal the victory.
Broncos 52, Eagles 20: The Broncos scored more points than they ever had in their 54-year history, led by Peyton Manning's four touchdown throws. With two TD passes each to Demaryius Thomas and Wes Welker, Manning completed all but a half-dozen of his 34 throws for 327 yards. He didn't even step on the field in the fourth quarter. Manning's 16 TD passes are the most in the first month of a season, besting the previous mark of 14 set by Don Meredith in 1966 and tied by Kurt Warner in 1999. Manning also joined Milt Plum in 1960 as the only quarterbacks to throw that many touchdown passes without an interception.
Manning got off to a rather slow start, but drove the Broncos (4-0) on a trio of long touchdown drives in the third quarter to make this one another laugher against the Eagles (1-3).
Chargers 31, Cowboys 20: Philip Rivers threw for 401 yards and three touchdowns, including a 56-yarder to Antonio Gates. The Chargers (2-2) had blown late leads in their two losses this season. On Sunday, they scored the final 20 points to beat Dallas (2-2).
Titans 38, Jets 13: Jake Locker threw a career-high three touchdowns before being taken to the hospital with an injured right hip. Locker was hurt early in the third quarter when hit first by Muhammad Wilkerson after throwing an incomplete pass, then popped by Quinton Coples. He grabbed at his hip as he went to the ground and was carted off the field before being loaded into an ambulance. The Titans had no immediate word on the severity of his injury.
Redskins 24, Raiders 14: Robert Griffin III threw a go-ahead touchdown pass late in the third quarter to help Washington overcome an early 14-point deficit for its first win of the season. David Amerson returned an interception for another score for the Redskins (1-3).
Bills 23, Ravens 20: Buffalo rookie linebacker Kiko Alonso's second interception of the game with 57 seconds remaining sealed a win over Baltimore. Converted safety Aaron Williams also intercepted Joe Flacco twice, while Fred Jackson had 87 yards rushing and a touchdown for Buffalo (2-2).
Cardinals 13, Buccaneers 10: Carson Palmer threw a 13-yard touchdown pass to Larry Fitzgerald, then Jay Feely kicked a 27-yard field goal with 1:29 remaining and Arizona rallied to beat Tampa Bay. Patrick Peterson had two interceptions, one setting up Arizona's first TD in six quarters, the other to ruin any chance of rookie Mike Glennon pulling off a comeback in his first NFL start for the winless Bucs (0-4).
Browns 17, Bengals 6: Brian Hoyer, the local kid who always dreamed of being Cleveland's quarterback, threw two touchdown passes in his first start at home to lead the Browns to a win over Cincinnati. Hoyer's 1-yard TD pass to Chris Ogbonnaya with 4:54 left gave the Browns (2-2) an 11-point lead and Cleveland turned it over to its vastly improved defense.
Chiefs 31, Giants 7: Alex Smith threw three touchdown passes, Dexter McCluster returned a punt 89 yards for another score and unbeaten Kansas City kept New York winless at 0-4. Smith hit touchdown passes of 4, 2 and 35 yards for the Chiefs (4-0), who under Andy Reid have already doubled their victory total of 2012. They are the second team to go from a two-win season to 4-0 the next year.
