The Miami Dolphins were without defensive tackle Paul Soliai last Sunday against the Atlanta Falcons because of a knee injury and they may be expecting him to miss a little more time based on a roster move they made on Monday.
Jason La Canfora of CBS Sports reports that the Dolphins have signed defensive tackle Marvin Austin. Austin was one of several free agent defensive linemen to work out for the Dolphins near the end of last week.
