At Assen he took the lead at the start, and led until Nicky Hayden passed him on the penultimate lap. He caught back up to his countryman on the last lap, and managed to pass him a few corners from the end. When Hayden attempted to pass him again in the final chicane, Edwards ran across the AstroTurf and lost control of his bike, which briefly continued on without him. He remounted to finish 13th. Hayden, who ran across the gravel on the final chicane himself, managed to keep control of his bike and won the race. At his home race, the Red Bull U.S. Grand Prix, Edwards finished ninth suffering tire problems in the scorching heat like his teammate Valentino Rossi. At Estoril he qualified second and finished fourth in one of his most competitive showings of the season.
