Busch, Logano escape discipline

CHARLOTTE, N.C.— NASCAR declined to penalize Kyle Busch, Joey Logano of their crews for their post-race scuffle at Las Vegas Motor Speedway on Sunday. The organization said the sport was built on the kind of racing that Busch and Logano did on the final laps, which led to Busch confronting Logano after the race and throwing a punch. Busch was knocked to the ground by Penske crew members. “The emotions of our athletes run high,” said NASCAR vice-president Steve O’Donnell.
