After the 2007 season Bell became an unrestricted free agent but he did not receive much interest from other teams because of his torn Achilles tendon. The Dolphins re-signed him to a one-year, 1.4 million dollar contract on March 3. In 2008, Bell became a force to be reckoned with. He finished the season with 120 tackles, 1 sack, and three forced fumbles, & while he did not have any picks that year, his return from injury proved to be the stabilizing force in the secondary.
