The Challenger Round of the Chase for the Sprint Cup comes to a conclusion this weekend at the high-banked, one-mile Dover International Speedway with the AAA 400.
At the end of 400 miles on Sunday, four drivers will be eliminated from championship contention while the remaining 12 Chase drivers will take the title fight to Charlotte Motor Speedway to kick off the Contender Round.
There are a total of 44 cars on the weekend's preliminary entry list, meaning one team will go home after Friday's knockout qualifying session.
