Defendant was convicted of two counts of delivery of a controlled substance, ORS 475.992(l)(a), and two counts of possession of a controlled substance. ORS 475.992(4)(a). He appeals, making three assignments of error. We address only the third assignment.

Defendant contends that, the trial court erred by delegating its sentencing authority to a probation officer. In addition to 60 days in jail time imposed on each conviction for delivery of a controlled substance, the court ordered, as a special condition of probation, that “defendant shall receive an additional 60 custody units to be utilized at the discretion of his probation officer”1 (Emphasis supplied.) Defendant argues that nothing in the sentencing guidelines authorizes the court to make such a delegation. The state agrees. We accept the state’s concession. OAR 235-05-012(3)(b); cf. State v. Stephens, 47 Or App 305, 312, 614 P2d 1180 (1980).

The condition of probation that 60 custody units are to be utilized at the discretion of a probation officer vacated and remanded for resentencing; otherwise affirmed.
