Cowboys quarterback Tony Romo was also in fine form as he launched five touchdown passes for 506 yards in the first 500-yard passing game in franchise history.
But the glory went to Matt Prater who kicked a 28-yard field goal as the clock ran down to seal the win and maintain Denver's perfect start to the season.

Matt Schaub was intercepted three times as the Houston Texans offence failed to fire in a 34-3 defeat to the San Francisco 49ers.

Two touchdown passes in the first quarter from Terrelle Pryor and an NFL record-tying 13th defensive touchdown from Charles Woodson helped the Oakland Raiders beat San Diego Charges 27-17 on the West Coast.
