Posted in The Colts have relinquished the rights to four restricted free agents, making them unrestricted free agents. Allowed to test their value on the open market are running back Mike Hart, tight ends Tom Santi and Gijon Robinson and defensive back Mike Richardson.
Safety Jamie Silva’s rights were also relinquised earlier today. The Colts have the right to issue one-year tenders to each of their restricted free agents – players with three years experience – but only did so with defensive lineman Eric Foster.
