Dolphins continue to tweak the roster

The Dolphins continue looking for special teams and any other kind of help as today they signed running back/fullback Lousaka Polite and apparently waived tackle Kirk Barton, who was absent from practice.

Polite was wavied by the Bears this week. His ties to the Dolphins are that he played for the Cowboys, who else, from 2004 to 2006.

He is 6-foot and 242 pounds and was signed as an undrated free agent by the Cowboys out of the University of Pittsburgh.

Adding Polite also protects the Dolphins because regular fullback Casey Cramer (ankle) missed Wednesday's practice and wasn't working during the time open to media today.

The Dolphins will announce this move later today.
