Kerry Collins threw two touchdowns, and Chris Johnson ran for 136 yards and a score as the Tennessee Titans routed the Cleveland Browns 28-9 Sunday to clinch the American Football Conference South and a second consecutive playoff berth with the franchise's best record through 13 games, 12-1. The Titans have won 15 of their last 16 games, and are the first team to secure a postseason berth this year. They maintained at least a two-game lead with three to play for home-field advantage in the AFC playoffs, clinched a first-round bye, and celebrated by dumping a cooler of Gatorade on coach Jeff Fisher with a minute left in the game. Ravens 24, Redskins 10: At Baltimore, Ed Reed set up a touchdown with an interception and scored on a 22-yard fumble return to help Baltimore beat Washington for its seventh win in eight games. Baltimore (9-4) also enhanced its stature in the wild-card race and remained one game behind Pittsburgh in the AFC North. Baltimore hosts the Steelers next Sunday. Cardinals 34, Rams 10: At Glendale, Arizona, Kurt Warner threw for 279 yards, the defense scored twice and Arizona clinched its first division title in 33 years by beating the woeful St. Louis to claim the National Football Conference West. The Cardinals, long the league's doormat franchise with just one winning season in the last 24 years, earned their first playoff berth since 1998 and first divisional title since they won the NFC East in 1975. Eagles 20, Giants 14: At East Rutherford, New Jersey, Brian Westbrook ran 30 yards for a touchdown, caught another 40-yarder from Donovan McNabb, and Philadelphia's defense limited the New York Giants to 211 yards and end the Super Bowl champions' seven-game winning streak. The Giants still clinched the NFC East when Dallas lost to Pittsburgh. Vikings 20, Lions 16: At Detroit, the Lions had chances to win, as they did in a two-point loss at Minnesota, but couldn't make enough plays, just as they have failed to throughout a miserable season. At this point, Detroit is expected to finish the season as the first 0-16 team in league history, with games remaining at Indianapolis, against New Orleans and at Green Bay. Steelers 20, Cowboys 13: At Pittsburgh, Deshea Townsend scored on a 25-yard interception return with 1:40 remaining as Pittsburgh scored its only two touchdowns 24 seconds apart to rally from a 10-point deficit.
