CHARLOTTE, N.C. (AP) Kyle Busch has been to victory lane 15 times this season. Only four of the trips were in his Sprint Cup car.
Those other 11 wins came in NASCAR's two lower-tier national series, much to the chagrin of die-hard race fans who believe the Xfinity and Truck Series should be for newcomers and development drivers.
On Wednesday, NASCAR announced a limit beginning next season for how many times veteran Cup drivers can moonlight at the lower level. A Cup driver with more than five years full-time experience will be restricted to 10 races in the Xfinity Series and seven races in the Truck Series.
