CONCORD, N.C. -- This weekend at Dover International Speedway, four drivers will be eliminated from the Chase for the NASCAR Sprint Cup.
That adds yet another wrinkle to the race at a track that Dale Earnhardt Jr. said can be one of the most difficult on the schedule.
"Dover is a very difficult race for the Chase," he said. "It's a tough track -- it's challenging for all the competitors. I don't think anybody really goes in there with huge confidence. Jimmie (Johnson) really does well there, but still, that track can be frustrating."
Earnhardt discusses the ins and outs of the track -- and what it takes to find success there -- in the video above.
"That concrete, it's a very, very difficult surface," he said.
