Green had four Top 15 finishes in 2004 (including a seventh-place finish in the Subway 500) and he would fail to finish in 11 races, the most DNF's in one season of his career; five were caused by engine failures while the other six were caused by crashes. The eventual 30th-place finish in the standings remains the lowest result for Green in a full-time season. He would continue to struggle in 2005. He failed to finish in the Top 10 the entire year, with his best finish being 11th in the Coca-Cola 600. Green's 29th-place finish allowed Petty Enterprises to announce on November 11, 2005 that Bobby Labonte would replace him following the season's end.
