In 2001, Green was announced as the driver of the #55 Davis & Weight Motorsports Ford Taurus in the Busch Series. After two top-twenty finishes early in the season, Davis & Weight announced it was closing its Busch team to run the Winston Cup Series. When that deal failed to materialize, Green ran out the remainder of the schedule for various teams, his best finish a ninth at Kansas Speedway for ST Motorsports. He also made his first Cup attempt at the NAPA 500 in the #41 for A.J. Foyt Racing, but failed to qualify.
