Three days later, defensive tackle Jesse Mahelona was waived after being inactive for one game with the team. Starting running back Ronnie Brown and starting free safety Renaldo Hill were both placed on injured reserve with torn ACLs suffered in the team's Week 7 game against the New England Patriots. Brown was leading the NFL in offensive yards at the time of the injury. On October 24, two of the three roster spots were filled from outside the organization as the Dolphins signed defensive end Quentin Moses and safety Lance Schulters.

He was inactive for six games before being waived. Schulters spent the latter part of the 2006 season with the Atlanta Falcons after starting for the Dolphins in 2005. Tight end Aaron Halterman was also promoted from the practice squad. Additionally, running back Samkon Gado was claimed off waivers from the Houston Texans.
