Owamagbe Odighizuwa signed his rookie contract on Friday, becoming the third member of the New York Giants 2015 NFL Draft class to do so.
Odighizuwa, a defensive end, was third-round pick. Safety Mykkele Thompson, a fifth-round pick, and seventh-round pick Bobby Hart, a guard, signed their contracts on Thursday.
That leaves first-round pick Ereck Flowers, second-round pick Landon Collins and sixth-round pick Geremy Davis unsigned.
The Giants began their rookie mini-camp on Friday with 66 players on the field at the Quest Diagnostics Training Center.
