For the rest of the season, Nadeau was hired by Petty Enterprises to drive Steve Grissom's No. 44 Dodge car, although he injured his ribs and shoulder in an go-kart accident at his home before the Old Dominion 500. He was advised by team owner Kyle Petty to rest, and Grissom replaced Nadeau for the rest of the season. He had competed in twenty-eight out of thirty-six races, with one Top Ten finish at the Food City 500, seven DNF's, and an average finish of 27.4. Nadeau finished thirty-seventh in the Winston Cup points standings for that season. He partnered sports car driver Anthony Lazzaro with the Rand Racing team in the Rolex Sports Car Series to finish first in the SRPII (Sports Racing Prototype) class at Daytona International Speedway, and in the Busch Series, he finished twentieth at the fall Charlotte race.
