The Green Bay Packers waived Harris on Monday. The 13-year veteran went unclaimed, allowing him to sign with any team. Harris was a Pro Bowler in 2007 and 2008, but he'll turn 36 in December and had a season-ending knee injury 12 months ago.
The Dolphins have been set at left cornerback with Vontae Davis, but they've been unsatisfied at right cornerback and nickelback -- not to mention with their ability to force turnovers.
Last year's right-side starter, Sean Smith, lost his job to Jason Allen just before the start of the regular season. Smith regained the job last week and dropped what would have been an interception for a touchdown in a loss to the Baltimore Ravens.
The Dolphins added cornerback Nate Ness off waivers last week.
Harris has started every one of the 102 games he played for Green Bay. He spent his first five seasons with the Philadelphia Eagles and has 21 career interceptions.
