The Miami Dolphins today placed safety Yeremiah Bell on injured reserve and waived defensive end Akbar Gbaja-Biamila, the team announced.
To fill the vacancies, the Dolphins signed free agent safeties Donovin Darius
and Lamont Thompson
. In addition, the team signed linebacker Kelvin Smith to its practice squad.
Bell suffered a ruptured left Achilles' tendon in the Dolphins' game last Sunday at Washington. He was coming off a 2006 season in which he started the final eight games and finished with 65 tackles, two sacks, two forced fumbles, two fumble recoveries and a team-high 12 passes defensed.
