The NASCAR O'Reilly's Auto Parts Series Bristol race was red flagged on Saturday due to a major engine fire involving Mason Maggio's No. 91 Chevrolet Camaro. The incident occurred on lap 194 near the start of Stage Three, resulting in a large engine fire that engulfed the track with smoke and spilled fuel on the track.
Maggio was helped from the car by infield safety crews without injury, but the failed engine brought out a red flag as the Coliseum around the half-mile track was filled with smoke. The incident occurred just days after Maggio's fifth start of the season, his third DNF this year.
The driver, Mason Maggio, had previously experienced engine failures at Daytona and Atlanta earlier in the season. Despite the setback, Maggio assured his mother watching from home that he was okay after the fire.

Maggio's team, Mario Gosselin, has been struggling with reliability issues throughout the season. The incident highlighted the risks of racing and the importance of engine durability.
The race resumed with Kyle Larson leading over last week's winner, William Sawalich. Larson swept the stages, mirroring his performance in last year's April race, which he went on to win.
Larson's victory marked a strong showing for the driver, who has been on a roll this season. The win was also notable for its similarity to his performance in last year's April race.
Connor Zilisch would go on to win his first O'Reilly's race since becoming a full-time Cup Series driver earlier this year, holding off Larson on older tires and battling with Brent Crews.
The incident serves as a reminder of the dangers of racing and the importance of safety protocols. Infield safety crews played a crucial role in responding quickly to the emergency.
As the season continues, teams will need to focus on improving engine durability and reliability to avoid similar incidents in the future.
