John Hunter Nemechek hated that he was the reason why Front Row Motorsports driver Zane Smith rode the Turn 4 wall while on his side at nearly 200 miles per hour. It all happened in overtime during Sunday’s Hollywood Casino 400 at Kansas Speedway.Smith was running the top lane entering Turn 3, alongside his teammate, Todd Gilliland. Right then, Nemechek dived in, hitting Smith’s left-rear quarter panel. In a shocking turn of events, Smith’s car slid further toward the fence and rammed straight into the SAFER barriers.Nemechek then squeezed Smith’s car into the wall, which then slid further for several yards. The Front Row Motorsports Mustang turned turtle, went airborne, and after two full rotations, landed on all four tires. Thankfully, Smith exited his No. 38 Mustang all by himself.However, his day had already ended. John Hunter Nemechek took to X (formerly known as Twitter) and apologized for whatever happened to Smith during the race.“My fault,” Nemechek wrote. “Made a mistake trying to make a move to go 3 wide into turn 3. apologies to the 38 guys and zane. hate the way it ended. a decent day but nothing to show for it.”Neither John Hunter Nemechek nor Zane Smith made the postseason this year. However, the drivers still have a shot at their maiden victory of the season. While Nemechek sits 26th in the driver standings with 590 points, Smith is ranked 27th with 537 points to his name.Next up for the drivers is the Bank of America ROVAL 400 at Charlotte Motor Speedway road course.

So I hate it. We were making ground on it all day,” he added.Chase Elliott won the race, marking his second victory of the 2025 season and his 21st overall. It also sealed his spot in the Round of 8.
