Peyton Manning threw for three touchdowns as the Indianapolis Colts rallied from a 13-point halftime deficit Sunday to clinch the American Football Conference South with a 35-27 win over the Houston Texans. It was their 20th straight regular-season victory Indianapolis, leaving the Colts is one win short of the New England Patriots' NFL-record 21-game run from 2006-08. The Colts can tie the record if they beat Tennessee at home next weekend. Manning threw two first-half interceptions, but had a pair of second-half TD passes, including a 4-yarder to Dallas Clark that gave the Colts a 21-20 lead with about nine minutes left. Titans 20, Cardinals 17: At Nashville, Tennessee, Vince Young hit a leaping Kenny Britt for a 10-yard touchdown as time expired, and Tennessee rallied for its fifth straight victory. Young won his ninth straight start and improved to 23-11 in his career by driving the Titans 99 yards in the final 2:37. He converted three fourth downs on the drive, two to Britt. He threw for a career-high 387 yards in outdueling Matt Leinart in their first meeting as professionals. Ravens 20, Steelers 17, OT: At Baltimore, an interception by rookie Paul Kruger set up a 29-yard field goal by Billy Cundiff with 6:42 left in the extra session, giving Baltimore a victory. Third-string quarterback Dennis Dixon started because Ben Roethlisberger was sidelined with a concussion and backup Charlie Batch had a broken left wrist. Dixon had thrown only one pass in two seasons before getting the nod against the Ravens. Chargers 43, Chiefs 14: At San Diego, LaDainian Tomlinson scored two touchdowns and moved into 10th on the NFL's career rushing list. Vikings 36, Bears 10: At Minneapolis, Brett Favre passed for a season-high 392 yards and three touchdowns, as the Vikings intercepted Jay Cutler twice. Favre went 32 for 48 without a turnover and was 10 yards off his career best, throwing touchdowns to Visanthe Shiancoe, Chester Taylor and Percy Harvin, the unflappable rookie who had his best game yet. 49ers 20, Jaguars 3: At San Francisco, quarterback Alex Smith threw short touchdown passes to Frank Gore and Vernon Davis in the kind of mistake-free day San Francisco coach Mike Singletary has sought for weeks. Bengals 16, Browns 7: At Cincinnati, newcomer Larry Johnson rushed for 107 yards in Cincinnati's conservative approach as the Bengals completed their first division sweep. Eagles 27, Redskins 24: At Philadelphia, David Akers kicked a 32-yard field goal with 1:48 remaining as Philadelphia rallied past Washington. Falcons 20, Buccaneers 17: At Atlanta, Chris Redman threw a 5-yard touchdown pass to Roddy White with 23 seconds remaining as Atlanta pulled out a victory after losing offensive stars Matt Ryan and Michael Turner to injuries. Bills 31, Dolphins 14: At Orchard Park, New York, a 56-yard field goal by Rian Lindell and a 51-yard touchdown catch by Terrell Owens in the final minutes propelled Buffalo. The win was the first for interim coach Perry Fewell, who replaced the fired Dick Jauron two games ago. Jets 17, Panthers 6: At East Rutherford, New Jersey, Darrelle Revis got the New York defense in the end zone for the first time this season. Seahawks 27, Rams 17: At St. Louis, Justin Forsett set career highs with 130 yards and two touchdowns as the go-ahead score came on the Seahawks' third defensive touchdown of the season.
