The Dolphins spent the day visiting with unrestricted free agent Vaughn Martin today, the team announced.
The 6-4 and 308 pound Martin fits as a five-technique defensive end but also a 4-3 defensive tackle which is where the Dolphins see value in him.
Martin is not really a pass-rusher. He three career sacks in four season -- one sack in each of the past three years.
Martin, 26, started 12 games for San Diego last year and 15 games in 2011.
