Kurt Busch to undergo Indy 500 rookie orientation:

It’s been 14 years since Kurt Busch was last called a rookie. And even though Busch has a Sprint Cup championship trophy at home, he’s still a rookie open-wheel driver as far as the Indianapolis 500 is concerned. That’s why Busch and four other drivers will take part in the rookie orientation or veteran driver refresher course to be eligible to compete in the May 25th Indianapolis 500 at Indianapolis Motor Speedway, the track announced Tuesday. Busch will join four other drivers - Mikhail Aleshin, Martin Plowman, Jack Hawksworth and 1995 Indy 500 winner and former CART and F1 champion Jacques Villeneuve - for the three-pronged orientation and driving program on Tuesday, April 29th and Monday, May 5th. Villeneuve will only have to complete the final two phases of the three-phase program to be recertified to race in the 500 because of his prior experience there. The orientation/refresher is designed that all five drivers can potentially complete all three phases in one day. If they are able to do so, the second day would be for practice - or if they need more instruction.(NBC Sports)(4-23-2014)
