Source: McDonald's to back McMurray

CHARLOTTE, N.C. -- Daytona 500 winner Jamie McMurray will be sponsored by McDonald's for 11 Sprint Cup races this season, beginning with Sunday's event at Las Vegas Motor Speedway, a source close to the situation tells ESPN.com.

The source said the deal has been in the works since last year and was not sparked by McMurray's win in the 500.

Earnhardt Ganassi Racing has been looking for a second primary sponsor since Bass Pro Shops, on McMurray's car for the 500, announced last season it was cutting back on the number of races it would sponsor the No. 1 car.

McDonald's is considered a natural fit for McMurray since his nickname has been "Big Mac" for a while.
