Last year, guard Donald Thomas appeared in 16 games and started 12 for the Dolphins.
This year, Thomas is a man without a team.
Though he has generated some interest, Thomas has yet to sign a contract. His next chance will come via a visit to the Steelers, per a league source.
Thomas entered the league as a sixth-round pick in 2008.
The Steelers also will be bringing in former West Virginia quarterback Jarrett Brown for a workout. And former West Virginia quarterback Pat White remains unemployed, by any football teams, that is.
