Pittsburgh Steelers rookie offensive tackle Max Iheanachor was at practice but was still in a limited capacity as the team prepares for its preseason opener. The Steelers yesterday signed two wide receivers to their training camp roster. Last year, he was on the UFL’s DC Defenders and helped lead the team to the league title. The other signee is Isaiah Winstead , who helped the Louisville Kings of the UFL win the title this year. Training camp continues today at Saint Vincent in Latrobe.
