During the next race in Denver, Tracy and French Newman-Haas driver Sébastien Bourdais, while fighting for second on the last lap, collided in a turn after Tracy attempted to pass. Bourdais shoved Tracy, who then took off his helmet and threatened to fight, and Bourdais walked away. Tracy was docked three points in the championship and was fined US$25,000. Bourdais demanded that Tracy be suspended, since he felt that Tracy had cost him several points that he could have used to widen his lead in the points standings over Tracy's teammate, A. J. Allmendinger.
