Tony Gibson was on the pit box of Kurt Busch’s No. 41 Stewart-Haas Chevrolet for just 22 laps Sunday at Bristol Motor Speedway. Then the rain came, delaying the continuation of the Food City 500 in Support of Steve Byrnes.
But before the race restarted 3 hours and 58 minutes later, Gibson found himself visiting a Bristol hospital for treatment regarding a kidney stone.
Gibson watched the rest of the race from his motor coach at the track and tweeted Monday he passed the stone in the early morning hours.
Gibson successfully passed another kidney stone March 17 in a hospital.
With Gibson replaced on the pit box by lead engineer John Klausmeyer, Busch went on to lead 98 laps before getting caught in a crash late in the race and finishing 15th.
