Matt Robinson, hired as the Giants' assistant defensive line coach, is leaving to become the Raiders' secondary coach, The Post confirmed.

Robinson, 32, spent the past five years with Harbaugh, most recently as the Ravens' outside linebackers coach.

He was brought in to work with Dennis Johnson, the Giants' defensive line coach, who previously held that position with the Ravens.

Instead, Robinson moves on to Las Vegas as a part of newly hired Klint Kubiak's first Raiders staff.

Robinson previously worked in Baltimore with Rob Leonard, the new Raiders' defensive coordinator.

Harbaugh had to give permission for Robinson to make this move, and he did so.
