A yellow flag at two upcoming NASCAR Sprint Cup Series races will generate some green to fight breast cancer.

Chevrolet will make a US$200 donation to the American Cancer Society for each caution lap that a specially themed pink Camaro SS pace car runs in upcoming NASCAR Sprint Cup Series races at Atlanta Motor Speedway and Richmond International Raceway. The Atlanta race begins 7:30 p.m. Sunday (televised on ESPN). The Richmond race is 7:30 p.m. Sept. 10 (televised on ABC).

Chevrolet's commitment to battling breast cancer won't stop on the track. In its centennial year, the brand is partnering with the American Cancer Society's Making Strides Against Breast Cancer initiative leading up to October, which is national Breast Cancer Awareness Month, and Chevy's Nov. 3 birthday. Other Making Strides Against Breast Cancer events will be announced later.

"For 100 years, Chevy has been helping people along the journey of life in countless ways," said Alan Batey, Chevrolet vice president, Sales and Service. "But as we all know, sometimes life's journeys take detours or end too early. Together with our race fans, Chevrolet wants to help the American Cancer Society create a world with less cancer, more birthdays and longer journeys."

Currently, Chevy driver Jimmie Johnson (No. 48) is tied for the lead in NASCAR Sprint Cup Series points. Johnson is the defending NASCAR Sprint Cup Series champion and winner of five consecutive championships.
