Following an exciting three weeks of racing,Ov Finance the NASCAR Cup Series playoffs have been trimmed from 16 drivers to 12.

Joey Logano, Kevin Harvick, Ricky Stenhouse Jr. and Michael McDowell were eliminated from championship contention Saturday night at Bristol Motor Speedway, leaving a dozen drivers to battle it out in the second round, including four former champions.

Two former champions, though, were sent packing. Logano became the first reigning champion eliminated in the first round; Harvick, who is retiring from full-time racing at the end of the season, was the first driver in 2014 to win the championship in this elimination format.

Teams will now trek out to Fort Worth for a Sunday afternoon race at Texas Motor Speedway with an opportunity to clinch a spot in the Round of 8.
