postponement

Persistent rain at Richmond International Raceway has forced NASCAR to postpone Saturday night's Sprint Cup race to Sunday afternoon.

Persistent showers in Kentucky meant that there was no opportunity to get the Quaker State 400 NASCAR Sprint Cup race underway on Saturday evening as planned.

Persistent rain forced the postponement of NASCAR's Coca-Cola 600 from its scheduled Sunday start, causing motorsport's biggest day to end in something of a damp squib.
