The Dolphins worked out three players on Friday, and one happens to be a former Cowboys starter.
Center Al Johnson, who started 31 games for Dallas before signing with Arizona as a free agent in 2007, participated in a tryout to fill the Dolphins vacant roster spot created by Greg Camarillo's season-ending knee injury.
Rookie fullback Chris Brown, and safety Herana-Daze Jones were also worked out by the Dolphins.
