Jeff Gordon brings perhaps the most impressive list of credentials of any driver ever competing in a fill-in role in the NASCAR Sprint Cup Series.
That doesn't mean, though, his transition into Dale Earnhardt Jr.'s car will be easy, or that he is necessarily the favorite to win at Indianapolis Motor Speedway this weekend.
Hendrick Motorsports announced Wednesday that Earnhardt will miss at least the next two races as he continues to recover from concussion-like symptoms. He missed last Sunday's race at New Hampshire Motor Speedway as well.
Gordon will drive at Indianapolis and Pocono.
