Jones was awarded off waivers to the Miami Dolphins on July 25, 2005. He was released following training camp and re-signed to the practice squad, but was placed on the active roster prior to the season opener. He went on to play in all 16 games in his first season with the Dolphins. On the season, he had 88 punts for a 43.5-yard average, including a net of 39.3, which led the NFL and marked a new Dolphins’ single-season record. He also added 31 punts inside-the-20, which ranked second in the AFC and was a Dolphins’ single-season record as well. Of his 88 punts, 24 went 50 yards or longer, with three traveling 60 yards or longer. He had a punt of 50 yards or longer in all but three games, and had a net average of 40.0 or better in nine games. He also held for placekicker Olindo Mare throughout the season. Jones' performance during the season earned him a selection as a third alternate for the Pro Bowl.
