THE SWITCHBACK?: NASCAR driver Parker Kligerman started his career in open-wheel cars. Now the 23-year-old is considering a move back. He would replace Busch in the Coca-Cola 600 if Busch doesn't make it back in time. ''I have a love for open-wheel cars and it's something that me and my manager Bob Perona have talked about,'' Kligerman said. ''I've been given a bit of a vacation right now, so I'm taking the opportunity as a race fan and a racer to see what's out there and what the possibilities are.''
