Rookie receiver James Washington signed his rookie contract Saturday.
Washington, a second-round pick out of Oklahoma State, is the fourth of the Steelers seven draft picks to sign. Running back Jaylen Samuels, safety Marcus Allen, defensive tackle Josh Frazier also signed their rookie deals this week.
First-round pick Terrell Edmunds and third-round picks Chukwumu Okoafor and Mason Rudolph are the only remaining unsigned draft choices.
All of the draft picks are taking part in the team’s rookie minicamp this weekend at the UPMC Rooney Sports Complex.
