The Miami Dolphins have announced the promotion of rookie linebacker Josh Kaddu off of the team's practice squad. Kaddu, the Dolphins' fifth round pick in last April's draft, was among the final roster cuts by the team at the end of the preseason and has been with the team's practice squad since.

The former Oregon Ducks linebacker will be asked to provide depth to the linebacker corps. The team is concerned about the health of starter Kevin Burnett, who has been battling a foot injury all season. The Dolphins are worried that, despite Burnett being limited in practice each week, the foot does not seem to be healing.

To replace Kaddu on the practice squad, the Dolphins have signed defensive end Louis Nzegwu. Nzegwu was a five year senior at Wisconsin, starting all 27 games his junior and senior seasons. The 6', 3", 254 pound defensive end ran a 4.57 second 40-yard dash at his Pro Day, impressing scouts. He was signed as an undrafted free agent by the Atlanta Falcons, spending the preseason with them before being waived.

The Dolphins play the St. Louis Rams this Sunday before heading into the bye week. The team could give Burnett three weeks to heal is foot if they hold him out of this week's game, letting him rest until the team faces the New York Jets on October 28 in New York.
