On lap 103, Gordon Johncock hit the wall coming out of turn four. He spun to the inside, hit the pit wall, then spun back across the pits and hit the wall separating the pits from the track. He missed hitting Teo Fabi's car, which was being pushed back to the garage, and somehow missed hitting the crew members that were in the sign board area. Johncock injured his left ankle (he had suffered a right ankle injury at Michigan the previous year), and ultimately took a short retirement from racing.
