Steelers withstand rally by Dolphins to win, 30-24

MIAMI -- The Pittsburgh Steelers barely hung onto a fourth-quarter lead -- and clung to their slim playoff hopes.

A swarming Steelers defense sent two Miami quarterbacks to the sideline, one (Pat White) with a scary head injury, and the reigning Super Bowl champions averted a late collapse to beat the Dolphins 30-24 Sunday.

The Dolphins (7-9), who won the AFC East in 2008, were eliminated with 2 minutes left in the game when Houston beat New England.

Houston's win hurt the Steelers' chances. To make the postseason, Pittsburgh (9-7) needed losses or ties by the Ravens, Broncos and Jets in late games Sunday.

The stadium grew silent when Dolphins rookie quarterback White was carted off with a head injury following a helmet-to-helmet collision with cornerback Ike Taylor. White moved his arms and legs before leaving the field after an eight-minute delay.
