CONCORD, N.C. - A scuffle broke out on pit road following Saturday's Carquest 300 NASCAR Busch Series race at Lowe's Motor Speedway, involving driver Brad Teague and James Caldwell, who works for driver Kevin Harvick.
According to witnesses, an angry Teague approached Harvick, who was sitting on the pit road wall, to complain about Harvick directing an obscene gesture toward him during the race.
Harvick listened and after telling Teague to leave, threw water in his direction. Teague became incensed and moved toward Harvick, but instead ran into Caldwell, knocking him to the ground while throwing punches, witnesses said. Teague was then pulled away from Caldwell and left the area.
Busch Series spokesman Rick Houston said officials were aware of the incident and that it was under investigation.
