NASHVILLE, Tennessee: Kerry Collins threw for a touchdown, Chris Johnson and LenDale White ran for a score apiece, and the Tennessee Titans routed the Pittsburgh Steelers, 31-14, in a showdown of the American Football Conference's best teams.

Tennessee clinched the top seeding and the home-field advantage throughout the playoffs.

The Titans improved the National Football League's best record to 13-2, but they were coming off a loss to Houston in which they failed to score a touchdown for the first time this year and were up against the NFL's stingiest defense.

They snapped back very well, ending the Steelers' five-game winning streak and becoming the first team to top 300 yards against Pittsburgh (11-4) this season.

They finished with 323 yards.
