ORDER

Clifton Flowers pleaded guilty to being in the United States without permission after he was removed following conviction for an aggravated felony. See 8 U.S.C. § 1326(a). He was sentenced to 84 months’ imprisonment and three years’ supervised release. Flowers now appeals his sentence, arguing only that the district court erred when it ordered him to submit to urine tests as a condition of his supervised release without specifying a maximum number of tests. Flowers correctly recognizes that the court, not the probation officer, must determine the required number of tests. 18 U.S.C. § 3583(d); United States v. Bonanno, 146 F.3d 502, 511 (7th Cir. 1998). However Flowers never objected to the drug-testing condition in the district court, so our review is for plain error. Fed.R.Crim.P. 52(b); United States v. Guy, 174 F.3d 859, 861 (7th Cir. 1999). The government concedes that delegation of judicial authority to a probation officer may constitute plain error, see United States v. Pandiello, 184 F.3d 682, *737 688 (7th Cir. 1999), and joins Flowers in urging that this case be remanded. But because one component of plain error is a manifestly unjust outcome, see United States v. Olano, 507 U.S. 725, 732, 113 S.Ct. 1770, 123 L.Ed.2d 508 (1993), Flowers cannot establish that the error here was plain. Flowers will be removed from the United States by the Department of Homeland Security when he completes his term of imprisonment, thus effectively ending his supervision and its required drug testing. Therefore no injustice has occurred.

AFFIRMED.
