The Broncos have won the past three meetings and the overall series is tied at five, including the playoffs.
Keep your eye on ...
Denver's first significant defensive test: The Broncos have played phenomenal defense this season and rank first in the league. That said, they have faced the league's worst two offenses the past two weeks and played against Cincinnati's 24th-ranked unit in Week 1. The challenge gets tougher this Sunday against the Cowboys' third-ranked offense.
Roy Williams' evolution as a No. 1 receiver: Slowly, but surely, Williams has become a bigger part of Dallas' offense. His four catches in Monday night's win over Carolina were his most in a Cowboys uniform and though he only has eight catches this season, he is averaging 22.4 yards per reception. He will need to come up big against a Broncos secondary that features Pro Bowl performers Champ Bailey and Brian Dawkins.
Dallas' ability to force turnovers: Through the first two weeks, the Cowboys defense had no sacks or takeaways. That changed against the Panthers as it tallied three sacks and three takeaways. It won't be as easy to force the Broncos offense into mistakes: Denver has only two turnovers all season and has given up only three sacks.
