Working with the rookie salary cap has removed suspense and coach Jeff Fisher has preferred to wait until all picks have agreed to terms before making a group announcement. The deals were announced Tuesday after the team's OTA workout.
Robinson, an offensive lineman, was the second overall pick and Donald, a defensive tackle, was taken 13th overall.
Also signing were defensive back Lamarcus Joyner, running back Tre Mason, safety Maurice Alexander, cornerback E.J. Gaines, quarterback Garrett Gilbert, offensive tackle Mitchell Van Dyk, safety Christian Bryant and center Demetrius Raney.
