Joe Gibbs Racing continues to dominate this year's chase as NASCAR heads to the Monster Mile-- Dover International Speedway Sunday for the AAA 400. Plus, another Waltrip Racing sponsor considers leaving and Kurt Busch gets a new paint job inspired by the film "Talladega Nights".

FOX News Radio's Marghiee Teshineh has this week's race preview:

This weekend the chase goes to Dover and Greg Biffle says trying to beat Joe Gibbs Racing's Matt Kenseth and Kyle Busch-- who are first and second in the chase standings won't be easy because:  

Biffle: "They have good momentum and they've got good, fast cars."

For Dale Earnhardt Junior though, winning a championship would be great.

Earnhardt Jr: "If we could win a couple of races no matter what happens in the championship, that will improve the results of our season and give us a lot to be happy about."

Will Michael Waltrip Racing lose another sponsor? 5-Hour Energy-- the primary sponsor of Clint Bowyer's car is said to be reviewing its options after the race manipulation scandal that resulted in fines, lost points and Martin Truex Junior losing his chase slot to Ryan Newman.

And, Kurt Busch is channeling Ricky Bobby and the movie "Talladega Nights" again. At next month's chase race at Talladega, Wonder Bread will sponsor Busch's car with a Wonder Bread paint scheme similar to the one in the movie.
