CONCORD, N.C. (AP) _ The only minority-owned team in NASCAR's top level is shutting down after losing its sponsor.

BelCar Racing fielded the No. 54 Ford for Todd Bodine this season. Sam Belnavis, who is black, was the majority car owner along with Travis Carter.

The team was sponsored by the National Guard, which signed Wednesday to sponsor Greg Biffle and the No. 16 Ford for Roush Racing. In announcing Biffle's new sponsor, the Roush team also introduced Belnavis as its director of diversity programs.

``I knew the direction the National Guard was taking,'' Belnavis said. ``But I needed a platform for my career but also a platform that could substantiate and support a true diversity program.''

Carter is trying to secure sponsorship for his own team.
