SEATTLE — With the Dallas Cowboys moving the ball near midfield and 14 seconds remaining in a tie game yesterday, Seattle kicker Josh Brown was preparing for overtime.

"I'm on the sideline trying to get mentally ready, trying to be by myself," Brown said. "It's one of those moments where you know what's coming. You know it's going to come. You just have to win the coin toss."

Instead of a coin toss, Seattle nickel back Jordan Babineaux tossed Brown's — not to mention the Seahawks' and Cowboys' — worlds upside down.

Babineaux intercepted Drew Bledsoe's sideline pass intended for Terry Glenn with 5 seconds left and returned it 25 yards to the Dallas 32.

Brown rushed onto the field and nailed a 50-yard field goal with no time left to give Seattle a 13-10 win.

Brown, who made a 55-yarder in the second quarter, threw his helmet into the Seattle mist and braced for the entire Seahawks roster, which was rushing him at midfield.

The thrilling turnabout was Seattle's third straight win and kept the Seahawks two games ahead of St. Louis atop the NFC West. They go into their bye week 5-2 for the sixth time in their 30-year history. Four times, they have made the playoffs after such a start. The fifth time, in 1986, they finished 10-6.

Dallas (5-3) fell out of the NFC East lead, a half-game behind three teams.

Seattle tied it at 10 with 40 seconds left when backup tight end Ryan Hannam caught quarterback Matt Hasselbeck's 1-yard TD pass while tumbling in the end zone.
