Dallas has taken three of the last four meetings and has a 5-3 overall series edge.
Keep your eye on ...
Romo's accuracy: The star quarterback has come under fire in recent weeks and has completed only 57.6 percent of his passes with one touchdown and four interceptions in his past three games. The critics figure to grown even louder if Romo struggles against the Chiefs' 28th-ranked pass defense.
DeMarcus Ware's production: The Pro Bowl linebacker led the NFL with 20 sacks in 2008 and averaged 13 sacks a year over his first four seasons. This year, Ware has yet to tally a sack. There is no better time for him to break out than against the Chiefs, who have already surrendered 13 sacks this season (the third-highest total in the league).
Matt Cassel's comfort level: Though the Chiefs quarterback has thrown four touchdowns in the past two weeks, he has struggled to get the ball downfield. He is averaging an anemic 4.5 yards per pass attempt over the last two games and Kansas City is just 2-for-26 on third down. Those stats must improve if the Chiefs are to spring the upset against the Cowboys.
