Rocky Shane Green has appealed the 18-month term of imprisonment imposed on revocation of his probation. Green contends that he should have been sentenced within the guideline-imprisonment range for the original offense of conviction, that is six to 12 months. Green concedes that the issue should be reviewed for plain error. In United States v. Pena, 125 F.3d 285, 287 (5th Cir. 1997), we held that, upon revocation of probation, the sentencing court is “not limited to the sentencing range available at the time of the initial sentence.” Any error by the district court could not have been “clear or obvious” in light of Pena. See United States v. Olano, 507 U.S. 725, 731-37, 113 S.Ct. 1770, 123 L.Ed.2d 508 (1993); United States v. Calverley, 37 F.3d 160, 162-64 (5th Cir. 1994) (en banc).

Green contends that his sentence was imposed illegally, in light of Blakely v. Washington, 542 U.S. 296, 124 S.Ct. 2531, 159 L.Ed.2d 403 (2004), and Apprendi v. New Jersey, 530 U.S. 466, 120 S.Ct. 2348, 147 L.Ed.2d 435 (2000), because he was sentenced to a term of imprisonment exceeding the term to which he was originally exposed based on the district court’s finding that he had violated a condition of his probation. Green concedes that this court’s review is for plain error. Green cannot show that the district court erred.

In Blakely, the Supreme Court held that the Sixth Amendment prohibits state sentences greater than “the maximum sentence a judge may impose solely on the basis of the facts reflected in the jury verdict or admitted by the defendant.” 542 U.S. at 303, 124 S.Ct. 2531 (emphasis omitted). The rule in Blakely was extended to the Federal Sentencing Guidelines in United States v. Booker, 543 U.S. 220, 125 S.Ct. 738, 160 L.Ed.2d 621 (2005). In Booker, the Supreme Court held that the mandatory system of enhancements established by the United States Sentencing Guidelines violated the Sixth Amendment. 125 S.Ct. at 749-50.

The policy statements applicable to probation revocations are advisory only and do not contravene the rule in Booker or the Sixth Amendment. See United States v. Hinson, 429 F.3d 114, 117 (5th Cir. 2005) (supervised release case); Pena, 125 F.3d at 287. Although the sentence exceeded the guideline range, see U.S.S.G. § 7B1.4(a), it was within the statutory maximum of 20 years for the offense of conviction. See Pena, 125 F.3d at 288. The district court stated that it wished to provide Green with an opportunity to participate in a comprehensive substance abuse treatment program provided by the Federal Bureau of Prisons. See id. at 287-88. The sentence was neither unreasonable nor plainly unreasonable and was not imposed in violation of law. See id.; see also Hinson, 429 F.3d at 119-20. The judgment is

AFFIRMED.
