Earnhardt Jr. opened the Challenger Round with a 12th-place finish at Chicagoland. At New Hampshire, he ran up front for most of the day, but an emergency fuel stop with two laps to go led him to finish 25th, two laps down, and at the bottom of the Chase cutline. At Dover, despite falling back at a few points, Earnhardt Jr. was locked in a battle with Jamie McMurray for control of the final transfer spot into the Contender Round. He almost did not make it into the next round, with his chances being saved thanks to a caution for Brett Moffitt's crash on lap 357 keeping him from having to make a green flag pit stop to replace a loose wheel. On the last restart, Earnhardt Jr. overtook McMurray on the outside, and finished third, clinching the final transfer spot and bumping McMurray out of the Chase.
