All roads of the racing community lead to Dayton on Sunday as the NASCAR Sprint Cup Series Coke Zero 400 Powered by Coca-Cola in partnership with NBC at the Daytona International Speedway gets underway.

USA Today said the weather is expected to be hot and humid during Sunday's race and it is expecting new storyline from NBC to highlight the competition.

The 57th annual Coke Zero 400 Powered By Coca-Cola NASCAR Sprint Cup Series will also kick-off NBC's return to NASCAR. The Sunday night date for the Coke Zero 400 will be only for the 2015 NASCAR Sprint Cup Series season with the Coke Zero 400 returning to Saturday night, July 2, 2016.

Daytona International Speedway president Joie Chitwood III expressed concern after Kyle Busch suffered injuries on his right leg and left foot from a crash into an unprotected barrier beyond pit road in the Xfinity Series season opener. Chitwood promised that every inch of the race track will be swathed in safer barriers.

Surprisingly, Busch made a remarkable comeback after the crash in his No. 19 Toyota Sprint Cup car.

On Thursday, the International Speedway Corp. and Speedway Motorsports Inc. - which own most of the tracks in the Sprint Cup Series, stretching from Florida to New York to California - as well as 30 specific tracks, have called on fans not to display the Confederate flat inside the Nascar facilities during the races to show their solidarity for the victims of the deadly shooting at a South Carolina church two weeks ago, reported The Gazette.

The statement read, "We are asking our fans and partners to join us in a renewed effort to create an all-inclusive, even more welcoming atmosphere for all who attend our events. This will include the request to refrain from displaying the Confederate flag at our facilities and NASCAR events."

Last week, Nascar said the Confederate flag is banned from being displayed from its events. Sunday's race will be the first to be held in the south following the shooting in Charleston that killed nine black churchgoers. The suspect had embraced the Confederate symbols including its flag during the attack.

Chitwood commented, "We want to be inclusive to everyone, and the last thing you want is for anyone to come to a sporting event and really not enjoy that experience because of symbols that really represent things we're not proud of.  Going forward, we'll really have to look at where that other flag goes, because it doesn't have a place in our sport and we've got to take a thoughtful process on how we get to that place."

Meanwhile, NASCAR has extended its thoughts and condolences to the family members and friends of Mary Scott, widow of Nascar Hall of Famer Wendell Scott and matriarch of the Scott family.

"Loved by all, she was a friendly and welcoming presence in the garage during her husband's competitive days in NASCAR. Her love and support provided Wendell a foundation for his many years of racing excellence, and helped guide his legend to NASCAR's pinnacle -- the NASCAR Hall of Fame," Nascar said in a statement.
