Saturday morning’s test session at the Roar Before the Rolex 24 was cut short after a massive airborne accident for the No. 50 Highway to Help Riley-Dinan DP in the Daytona tri-oval.

Byron DeFoor was at the wheel of the Daytona Prototype when eyewitnesses said it suddenly spun backwards, caught air and went into the catch fence.

The car landed upside down on its roof on the racing surface entering Turn 1. DeFoor was taken to the infield medical center and per IMSA, was evaluated and released.

Per a Continental Tire spokesperson, it was reported that the right rear lost air pressure, which sent the car into a spin through the infield. As this was an isolated incident, there have been no other issues reported.

DeFoor co-drives this weekend with David Hinton, Jim Pace and Dorsey Schroeder, the last of whom is set to make his racing return for the first time since the 1990s.
