Chip Ganassi Racing driver Kurt Busch called Sunday’s hard wreck into the wall at Las Vegas Motor Speedway a “devastating blow” — and one that significantly impacts his playoff standing.

The Chip Ganassi Racing driver made contact with eventual race winner Martin Truex Jr. and Chase Elliott, which caused a tire rub and sent his No. 1 Chevrolet hard into the wall on Lap 188.

The veteran and 2004 series champion finished last in the 39-car field.

The poor points day dropped Busch from eighth in the standings to 14th with two races remaining in the Round of 16. Following the Charlotte Roval race on Sept. 29, four drivers will be eliminated from the postseason field.

Busch currently is 14 points behind the cutline, but as he also noted in his tweet, the entire No. 1 team “are fighters” and have produced fast race cars.

The team will have its opportunity for redemption Saturday night at Richmond Raceway, where Busch has two wins in 37 career starts.

LAS VEGAS — Kevin Harvick’s runner-up finish in Sunday’s NASCAR Playoffs opener wasn’t quite the dominant show of strength he flexed in the previous week’s victory at Indianapolis. Instead, the hard-fought outcome was part of a weekend-long recovery effort.

Harvick’s No. 4 Stewart-Haas Racing Ford led three times for 47 laps in Sunday’s South Point 400 at Las Vegas Motor Speedway, holding the top spot until eventual winner Martin Truex Jr. scooted past with 20 laps remaining. The work that went into turning the tide was nearly Herculean, based on wholesale changes to improve the No. 4 car’s handling and balance.

“If you’d have told me at the end of Friday night that we were going to be in contention to win the race with 25 laps to go, I’d have laughed at you,” Harvick said. “I’d have told you we were nowhere even close, and the guys did a great job scrambling and doing everything that they could to keep changing stuff and keep making the car better. We made our car better throughout the race.”

Harvick’s comeback story has origins dating back to Friday’s two practices, when the team improved from 18th on the speed chart in first practice to seventh in the final session. By the time Saturday’s Busch Pole Qualifying rolled around, Harvick claimed the third starting spot as part of a top-four sweep by Stewart-Haas drivers after major alterations to get the No. 4 entry in proper form.

Shortly after the green flag fell Sunday, Harvick drove away from a fairly benign brush with the outside wall on Lap 17. By Lap 84 of 267, the veteran driver was in the lead for the first time.

Though Harvick nearly converted for his second straight Monster Energy Series win, crew chief Rodney Childers indicated there was plenty to take away from the first weekend in the 10-race playoffs.

“We didn’t build the right cars for here, and it was horrible when we unloaded,” Childers told NASCAR.com. “That’s something we’ve got to do better as a company. Fortunately, the 4 team is strong enough to work hard all weekend and do the right things to make the car better and have a good race, but the only way we’re going to hold (Truex) off is to have a caution at the right time and have clean race tracks and not have to pass lapped cars.

“Their cars just had way more grip than ours all weekend and that’s something that we struggled with at Darlington also, and we turned around and did the same thing there, fought through it and got a top five out of it. So honestly to finish second from where we unloaded is huge.”

Harvick carried the torch for the rest of the SHR bunch — teammate Aric Almirola secured 13th, with Daniel Suarez 20th and pole-starter Clint Bowyer fading to a 25th-place result. But it was the No. 4 team’s ability to claw through adversity — a valuable asset for championship-ready teams — that seemed to stick with Harvick the most.

“We were a 20th-place car on Friday and today we ground one out,” said Harvick, who logged his third straight top-five result. “So that’s what you have to do on the weekends where you’re not where you need to be. You’ve got to figure out how to make something out of it and we did.”

The race-winning No. 19 Joe Gibbs Racing Toyota driven by Martin Truex Jr. passed post-race technical inspection Sunday at Las Vegas Motor Speedway with no issues.

The No. 19 Toyota was found to be compliant with the 2019 NASCAR Rule Book after Truex Jr. won the NASCAR Playoffs opener, the South Point 400. Additionally, no cars are headed back to the R&D Center after the race.

Three cars were found to have one lug nut missing: The No. 10 Stewart-Haas Racing Ford of Aric Almirola (finished 13th), the No. 18 Joe Gibbs Racing Toyota of Kyle Busch (finished 19th) and the No. 88 Hendrick Motorsports Chevrolet of Alex Bowman (finished sixth). Those will result in fines to the respective team’s crew chiefs.

With post-race teardown complete, the race results are official.

The post-race process is part of a new, more timely approach to inspection for all three NASCAR national series. Competition officials announced in February that thorough post-race inspections would take place shortly after the checkered flag at the track instead of midweek at the NASCAR Research & Development Center in Concord, North Carolina.

Those inspections come with a stiffer deterrence structure that includes disqualification for significant rules infractions — “a total culture change,” according to Steve O’Donnell, NASCAR Executive Vice President and Chief Racing Development Officer. In the past, race-winning teams found in violation of the rules were penalized with post-race fines, points deductions and/or suspensions, but victories were allowed to stand.

Competition officials introduced the quicker post-race inspection timetable in an effort to make the results official on race day, aiming for a 90-minute target time frame to complete their scrutineering. The new post-race inspection process was also designed to deal with potential violations more promptly, avoiding any midweek news that might cloud the previous week’s results or the build-up to the following week’s event.

NASCAR will still inspect cars and parts at the R&D Center as needed, but the more comprehensive at-track inspection will take priority.

According to NASCAR statistical archives, the last time a premier-series driver was disqualified occurred in 1973, when early retiree Buddy Baker was demoted to last place in the National 500 at Charlotte Motor Speedway. The last time an apparent race winner in NASCAR’s top division was disqualified came on April 17, 1960, when Emanuel Zervakis’ victory at Wilson (N.C.) Speedway was thrown out because of an oversized fuel tank on his No. 85 Chevrolet.
