NASCAR goes to Dover International Speedway this Sunday for the AAA Drive for Autism 400 and Kyle Busch loses his crew chief this weekend.

FOX's Marghiee Teshineh with "FOX In The Fast Lane":

Driver Martin Truex Jr. says there is a bonus to racing this weekend at his 'home track' of Dover:

(Truex Jr.) "I love going there, love racing there and you know, we gotta a lot of friends and family that come, that always adds some incentive to try and get the job done on Sunday."

Truex looking for his first win of the season says he has no doubts about his team and the cars they are giving him to get him to Victory Lane:

(Truex Jr.) "Certainly we expect to make the Chase, we expect to win races. The way we've run this year, I feel like it won't be long, we're going to start winning again, we've been so close."

Ahead of this weekend's race, Dover officials have added an additional 479 feet of safer barriers, including 78 feet to the inside backstretch.

And NASCAR has suspended Kyle Busch's crew chief Adam Stevens and front-tire changer Josh Leslie for one race for violating the lug nut policy at Kansas Speedway. Stevens was also fined $20,000 and placed on probation until the end of the year.
