William Byron’s promising run on Sunday at Las Vegas Motor Speedway ended in devastation after a collision late in the race, dramatically altering his NASCAR Cup Series championship trajectory. The William Byron Las Vegas crash left his No. 24 Hendrick MotorsportsChevrolet battered and dropped him out of immediate Championship 4 contention with the playoffs nearing their decisive phase.
Byron’s Strong Start Sours After Sudden Incident
Starting from the fifth position at Las Vegas Motor Speedway, William Byron quickly established himself as a contender, leading 55 laps and maintaining a spot near the front of the pack for much of the day. Hopes for a top finish appeared well-founded until disaster struck on Lap 235 of 267. Unaware that Ty Dillon, who was not in playoff contention, was slowing to enter pit road, Byron had little time to react. The resulting impact sent Byron hard into the back of the No. 10 Kaulig Racing Chevrolet, sending shockwaves through the crowded field.

“He just started slowing. And I had no idea what was going on. I’m just devastated. I had no indication. Obviously, I wouldn’t have just driven full-speed into the back of him like that.”

Playoff Prospects Take a Major Hit
The violent collision forced Byron to retire from the race, parking his car in the garage and marking his first DNF since July. For a driver who won the last two Daytona 500s, such a setback was not only rare but also costly. Byron finished a distant 36th out of the 38 starters, falling from being just inside the Championship 4 cut line to trailing bubble driver Chase Briscoe by 15 points.
This reversal comes at a crucial point: with only two races remaining in the Round of 8, Byron must recover ground to secure a spot in the final race at Phoenix Raceway, where the season’s champion will be crowned. Heading into Las Vegas, Byron held a slender four-point advantage over the first man out, but the William Byron Las Vegas crash has left him in desperate need of strong results in the upcoming events to keep his title aspirations alive.
Byron’s Reflections and Emotional Fallout
The aftermath of the crash was filled with disappointment and visible frustration from the Hendrick Motorsports driver. Byron reflected on losing the lead just before the accident, saying,
“I got loose a few laps before (the accident) and lost the lead, which I was bummed about,”
—William Byron. He tried to regain rhythm, adding,
“But I was going to try and get my (car’s) balance back to a reasonable place. I was a little bit loose that run, looser than I was expecting to be. And I was just kind of pacing it.”
—William Byron.
Despite the setback, Byron believed his car was capable of competing with teammate Kyle Larson, who eventually finished second behind Denny Hamlin, the race winner. Byron voiced the difficulty of accepting his fate, stating,
“With as good as we were and as good as the race was going, for random things like that to happen, it just sucks,”
and
“I can’t believe it. It just sucks.”
—William Byron.
After the accident, Byron addressed the media, continuing to express surprise about Ty Dillon’s pitting, a detail that remained unclear even in post-race interviews.
