MIAMI (CBSMiami.com) – The Miami Dolphins have had safety issues for the past four years and tried to boost the position Wednesday by signing free agent Gerald Alexander.

Alexander has played for the Carolina panthers, Jacksonville Jaguars, and Detroit Lions since 2007. He’s played in a total of 41 games and started 30 of them.

For his career, Alexander has four interceptions, two sacks, four fumble recoveries, three forced fumbles and 14 passes defensed.

In order to sign Alexander, the Fins placed wide receiver Roberto Wallace on injured reserve, which means Wallace is done for the season.
