IRVING, Texas — New Washington Redskins coach Jim Zorn was looking for something to help him build up a healthy dose of hate for the Dallas Cowboys. Turns out, he kinds of likes playing his team's archrival.

Jason Campbell threw two touchdown passes and Clinton Portis ran for 141 yards, leading the Redskins to a 26-24 victory today that knocked the Cowboys from the ranks of the unbeaten.

Washington (3-1) won for only the second time in its last 13 visits to Texas Stadium. With Dallas moving to a different suburb next season, this was the Redskins' last visit to a place that rarely treated them well. Thus, unless Washington returns for a playoff game, Zorn will have the unique distinction of being undefeated here.

More importantly, the Redskins proved the two-game winning streak they brought in wasn't just a byproduct of playing bad teams. They're legit, and that means the NFC East — already the best division in the NFL — is now a four-way race.

Zorn had to sweat it out, though. After Washington went up 26-21 with 3:22 left, Tony Romo marched Dallas 82 yards in eight plays, capping it with an 11-yard touchdown to Miles Austin. The Cowboys went for an onside kick and the ball came up high and catchable for receiver Sam Hurd but he wasn't able to hold it, losing the ball out of bounds. While team owner Jerry Jones grimaced on the sideline, Redskins owner Dan Snyder was certainly celebrating.
