Chastain’s COTA Run Implodes As NASCAR Hands Down Two Crew Suspensions

Ross Chastain arrived at Circuit of the Americas with the kind of momentum that usually turns into a strong Sunday. He qualified on the outside of the front row. He won Stage 1 with authority. The No. 1 Chevrolet looked settled, fast, and capable of running with anyone in the field.

For most of the afternoon, Trackhouse Racing had every reason to believe they were building toward a finish that would help shape the early part of their season. Instead, the race unraveled in a single moment. A right‑rear wheel came off the car, and everything Chastain had built over the first two stages collapsed in seconds.

What should have been a top‑ten day turned into a 35th‑place finish. And now, two members of his pit crew will miss the next two races after NASCAR issued suspensions for the loose wheel. The fallout from COTA is still settling, and the impact will stretch into Phoenix and Las Vegas.

How Chastain’s Race Fell Apart

Chastain was running inside the top ten after the final round of green‑flag pit stops. The car still had speed. The balance was there. The team had executed well enough to stay in the fight. Then, entering Turn 19, the No. 1 Chevrolet snapped sideways and slid into the gravel. The right‑rear wheel had separated from the car entirely.

The moment was jarring. A Cup car losing a wheel at speed is violent, unpredictable, and dangerous. Chastain fought the car the entire way through the slide. Somehow, he kept it moving and clawed his way back to pit road. That alone took skill. A three‑wheeled Cup car is almost impossible to control, especially on a road course where the surface changes corner to corner.

But the damage was already done. The detached wheel rolled across the circuit and forced the only caution of the entire race. NASCAR hit Chastain with a two‑lap penalty. With the race running green the rest of the way, there was no chance to recover. The day was gone.

For a driver who had shown speed from the moment he unloaded, the frustration was obvious. COTA had been shaping up to be one of his cleanest, most complete races of the young season. Instead, he left Austin with a finish that will linger in the standings for weeks.

NASCAR’s Penalties For The No. 1 Team

After reviewing the incident, NASCAR issued suspensions to two members of Chastain’s pit crew. Jackman, Josh Appleby, and rear tire changer Kenneth Pozega will miss the next two Cup Series races. That means they will sit out Phoenix Raceway and Las Vegas Motor Speedway. Two races. Two critical positions. Gone.

This was the only penalty NASCAR handed out across the entire COTA weekend, including the Cup race and the Truck Series event at St. Petersburg. The sanctioning body made it clear that loose wheels remain one of the most serious violations in the sport.

The rule is simple. If a wheel comes off, the suspension follows. NASCAR has been consistent about that since the introduction of the Next Gen car. The single‑lug design demands precision. Teams know the procedures. Crews know the stakes. When a wheel detaches, the responsibility is clear.

For Trackhouse, this was the first time the No. 1 team had been penalized for a loose wheel. They are not known for sloppy pit work. This was a rare mistake on a day when everything else had been trending in the right direction.

Why Loose Wheels Carry Heavy Consequences

A loose wheel is not a small error. It is a 60‑pound object traveling at race speed. If it bounces the wrong way, it can hit a competitor, break through a fence, or reach the stands. NASCAR has dealt with the consequences of loose wheels before, and the risks are too high to ignore. Since the Next Gen car arrived in 2022, NASCAR has issued dozens of loose‑wheel penalties.

The sanctioning body has made it clear that safety comes first. The rule exists to prevent the kind of incident that could change the sport forever. The No. 1 team knows that. Every team does. That is why the penalty stings. It was preventable. It was costly. And it came on a day when Chastain had the speed to run near the front.

What This Means for Chastain And Trackhouse

Losing two experienced pit crew members for back‑to‑back races is a real problem. Pit road execution is everything in the Cup Series. Phoenix is a track where passing is difficult, and track position is almost everything. Las Vegas is a place where a half‑second on pit road can swing a driver from the top ten to the mid‑pack.

Chastain already absorbed the damage from COTA. He started near the front. He won a stage. He had the pace to run inside the top ten. Instead, he left Austin with a 35th‑place finish and a crew that now needs reinforcements.

Trackhouse will have to assemble a replacement pit unit for two of its most important roles. Whoever steps in will be under pressure immediately. There is no easing into Phoenix. There is no margin for error in Las Vegas. The team will need to adjust quickly, communicate clearly, and trust that the temporary lineup can hold the line.

From a championship standpoint, the COTA result is a setback. Chastain is a driver capable of winning races and stacking playoff points. Days like this matter. Not just because of the finish, but because of how close the team was to something meaningful before it unraveled.

The psychological impact matters too. Drivers feel it when a strong day slips away. Crews feel it when a mistake changes the outcome. Teams feel it when momentum disappears in an instant. Trackhouse has built a reputation for resilience, but this stretch will test them.

What’s Next

Sunday’s COTA incident at COTA proves how unpredictable and unforgiving NASCAR can be. One loose wheel changed the entire trajectory of Chastain’s weekend. It cost him a strong finish. It triggered penalties that will follow the team into the next two races. And it forced Trackhouse to regroup at a time when momentum matters.

Appleby and Pozega will watch Phoenix and Las Vegas from home. The rest of the No. 1 team will carry the load in their absence. Chastain will try to keep himself in the playoff conversation with a short‑handed crew behind him. The sport does not slow down. There is no pause button after a day like COTA. Phoenix is coming. Las Vegas is coming. The pressure only gets heavier from here.
