Matt Kenseth meets fan who hopped fence during red-flagged NASCAR race

Matt Kenseth met the fan who vaulted the fence during a red-flagged NASCAR Cup Series race at San Diego’s Naval Base Coronado on Sunday.

A fan climbed the fence and ran onto the track during a red-flag stoppage at the 2025 NASCAR Cup Series race held at Naval Base Coronado in San Diego on Sunday. NASCAR officials halted the race under caution, and the intruder crossed the barrier before being detained by security. The race resumed after the track was cleared.

Matt Kenseth, who drove the No. 11 Chevrolet for Joe Gibbs Racing, was among the drivers present when the incident unfolded. The red flag lasted nearly 20 minutes while crews restored order and removed the trespasser.

For Kenseth, the moment added an unusual layer to an already unique event. The race at Naval Base Coronado is one of NASCAR’s most distinctive stops, held on a temporary street course inside a military base. Kenseth, a two-time Cup Series champion, has raced there before and knows the track’s tight confines and high stakes.

The intrusion forced a pause in the action and drew extra attention to Kenseth’s team. Joe Gibbs Racing had to regroup during the red flag, adjusting strategy without knowing how long the delay would last. Kenseth’s crew chief, Chris Gabehart, later called it “a curveball we didn’t plan for.”

NASCAR has launched an investigation into how the fan breached security and accessed the track area. The agency will review camera footage and access logs to determine gaps in protocol. Penalties against the track or security firm could follow if negligence is found.

Kenseth and the No. 11 team returned to pit road after the race resumed. They finished 14th in the 36-car field. The Cup Series now turns to the next stop on the schedule, the 2025 Quaker State 400 at Atlanta Motor Speedway on July 20.
