OPINION
Santos Matamoros-Modesta appeals in No. 07-4105 from his thirty-seven-month sentence for illegal reentry into the United States after removal, in contravention of the Immigration and Nationality Act (the “INA”), specifically 8 U.S.C. § 1326. Matamoros-Modesta maintains that the district court erred — in the wake
of
the Supreme Court’s decision in
Lopez v. Gonzales,
I.
On July 27, 2005, a grand jury in the Western District of North Carolina charged Matamoros-Modesta in a single-count indictment with the INA offense of illegal reentry. The indictment specified that he was charged under 8 U.S.C. § 1326(a) and (b)(2). 2 On March 7, 2006, Matamoros-Modesta pleaded guilty to the *262 offense as charged, without a written plea agreement. Thereafter, a presentence investigation report (the “PSR”) was prepared for him. Applying the 2005 edition of the Sentencing Guidelines, the PSR assigned Matamoros-Modesta a base offense level of 8. See USSG § 2L1.2(a). The PSR then added an eight-level enhancement for having previously been removed following “a conviction for an aggravated felony.” Id. § 2L1.2(b)(l)(C) (the “aggravated felony enhancement”). The PSR reflected two possible bases for the aggravated felony enhancement: (1) a 1998 conviction in Texas for possession of cocaine, and (2) a prior federal conviction in 2004 for illegal reentry. 3 Finally, the PSR awarded a three-level adjustment for acceptance of responsibility, id. § 3E1.1, resulting in a total offense level of 13. With a criminal his-tory category of V (based on a total of twelve criminal history points), the resulting advisory Guidelines range was thirty to thirty-seven months of imprisonment. The PSR identified the maximum statutory prison term as twenty years, citing subsection (b)(2) of 8 U.S.C. § 1326.
On December 18, 2006, the district court conducted a sentencing hearing for Mata-moros-Modesta. At the start of the hearing, the court reaffirmed its acceptance of Matamoros-Modesta’s guilty plea. Next, the court adopted the PSR, without objection from the parties (or any mention of the Supreme Court’s decision in Lopez v. Gonzales, which had been issued two weeks earlier, on December 5, 2006). After considering the Sentencing Guidelines, as well as the factors set forth in 18 U.S.C. § 3553(a), the district court imposed a sentence of thirty-seven months, at the high end of the Guidelines range. The court’s Judgment reflects that Matamoros-Modes-ta was deemed guilty of and sentenced for illegal reentry, in contravention of 8 U.S.C. § 1326(a) and (b)(2). Matamoros-Modesta timely noted this appeal, which he has since limited to a Lopez-based challenge to his sentence. 4
II.
As a result of the Supreme Court’s decision in
United States v. Book
*263
er,
A.
In
Lopez v. Gonzales,
the Supreme Court assessed “whether conduct made a felony under state law but a misdemeanor under the Controlled Substances Act is a ‘felony punishable under the Controlled Substances Act’ ” — and, thus, whether such a state offense is an “aggravated felony” for purposes of the INA.
See
As the Court recognized, the INA makes an alien “guilty of
an
aggravated felony if he has been convicted of ‘illicit trafficking in a controlled substance ... including,’ but not limited to, ‘a drug trafficking crime (as defined in section 924(c) of title 18).’ ”
Lopez,
The petitioner in
Lopez
was contesting the Government’s determination that he was deportable, pursuant to the INA (specifically, 8 U.S.C. § 1227(a)(2)(A)(iii)), as an “alien who [was] convicted of an aggravated felony at any time after admission.”
See
B.
Matamoros-Modesta challenges the district court’s imposition of the aggravated felony enhancement under section 2L1.2(b)(l)(C) of the Sentencing Guidelines, with respect to his sentence for illegal reentry in contravention of the INA, 8 U.S.C. § 1326. By contrast, the petitioner in
Lopez
contested an aggravated felony determination that disqualified him under the INA, 8 U.S.C. § 1229b(a)(3), from discretionary cancellation of removal. The
Lopez
holding is clearly pertinent, however, to Matamoros-Modesta’s sentencing contention. That is, both 8 U.S.C. §§ 1326(b)(2) and 1229b(a)(3) rely on the INA definition of aggravated felony found in 8 U.S.C. § 1101(a)(43), subparagraph (B) of which was interpreted by the
Lopez
Court. Moreover, as the
Lopez
Court acknowledged, the Sentencing Guidelines have adopted that same INA definition of aggravated felony for purposes of imposing the aggravated felony enhancement.
See
Under
Lopez,
the district court’s determination that Matamoros-Modesta had been removed subsequent to an aggravated felony conviction constitutes error. As noted above, Matamoros-Modesta’s PSR reflected two possible bases for the aggravated felony enhancement, i.e., his 1998 conviction in Texas for possession of cocaine, and his prior federal conviction in 2004 for illegal reentry. The Texas drug possession offense, though deemed a felony under state law, was not punishable as a felony under the federal Controlled Substances Act and, thus, cannot satisfy the INA definition of an aggravated felony found in 8 U.S.C. § 1101(a)(43)(B) and interpreted in
Lopez. See Lopez,
III.
Pursuant to the foregoing, we vacate Matamoros-Modesta’s illegal reentry sentence, and remand for resentencing.
VACATED AND REMANDED
Notes
. Matamoros-Modesta also noted appeals in No. 07-4105 from his conviction for illegal reentry, and in No. 07-4118 from a revocation of supervised release and the resulting 366-day sentence. We do not consider these matters herein, however, because Matamo-ros-Modesta abandoned his challenge to the illegal reentry conviction by renouncing it at oral argument.
See Synergistic Int’l, LLC v. Korman,
. Subsection (a) of § 1326 provides, "[s]ub-ject to subsection (b),” that any alien who—
(1) has been denied admission, excluded, deported, or removed or has departed the United States while an order of exclusion, deportation, or removal is outstanding, and thereafter
(2) enters, attempts to enter, or is at any time found in, the United States, unless (A) prior to his reembarkation at a place outside the United States or his application for admission from foreign contiguous territory, the Attorney General has expressly consented to such alien’s reapplying for admission; or (B) with respect to an alien previously denied admission and removed, unless such alien shall establish that he was not required to *262 obtain such advance consent under this chapter or any prior Act,
shall be fined under Title 18, or imprisoned not more than 2 years, or both.
Subsection (b), in turn, outlines enhanced criminal penalties for certain offenders. Under subsection (b)(2), "in the case of any alien ... whose removal was subsequent to a conviction for commission of an aggravated felony, such alien shall be fined under [Title 18], imprisoned not more than 20 years, or both.”
.The PSR also revealed that Matamoros-Modesta, while a juvenile, had been removed from the United States on November 19, 1997, after entering the country illegally. Matamoros-Modesta illegally reentered the United States and, after his 1998 conviction in Texas for cocaine possession, was removed on June 11, 1999. Following another illegal reentry into the United States, he was convicted of a number of offenses in South Carolina and North Carolina between 2000 and 2003. He also received his prior federal conviction in 2004 for illegal reentry. On March 17, 2005, Matamoros-Modesta was again removed. He illegally returned to the United States sometime between his last removal and his July 14, 2005 arrest on additional North Carolina charges of which he was subsequently convicted.
.Notably, although the indictment charged the INA offense of illegal reentry pursuant to 8 U.S.C. § 1326(a) and (b)(2), and the district court’s Judgment reflects conviction under those same provisions, the Supreme Court has recognized that the substantive crime of illegal reentry is defined in subsection (a), and not subsection (b)(2).
See Almendarez-Torres v. United States,
. The parties have agreed that the district court committed plain error in sentencing Matamoros-Modesta.
See
Fed.R.Crim.P. 52(b) (providing that "[a] plain error that affects substantial rights may be considered even though it was not brought to the court's attention”);
United States v. Olano,
. The INA defines "aggravated felony” in 8 U.S.C. § 1101(a)(43), which includes subpar-agraphs (A) through (U). The Lopez Court focused on subparagraph (B), which renders "illicit trafficking in a controlled substance” an aggravated felony.
. In so holding, the Supreme Court overruled our contrary decision in
United States v. Wilson,
. The
Lopez
Court acknowledged that the general proposition that the Controlled Substances Act punishes drug possession offenses as misdemeanors is subject to a few exceptions for, e.g., repeat offenders, persons who possess more than five grams of cocaine base, and persons who possess flunitrazepam.
See
. The
Lopez
Court also allowed that a state felony would satisfy the INA definition of aggravated felony found in 8 U.S.C. § 1101(a)(43)(B) if it "actually fell within the general term 'illicit trafficking,’ ... regardless of the existence of a federal felony counterpart.”
. Matamoros-Modesta has acknowledged that he is subject to a four-level enhancement under section 2L1.2(b)(1)(D) of the Sentencing Guidelines, for having previously been removed following "a conviction for any other felony.” Assuming all other Guidelines calculations stand (except a necessary change from a three- to a two-level adjustment for acceptance of responsibility, see USSG :§ 3E1.1), Matamoros-Modesta would have an offense level of 10, a criminal history category of V, and a resulting sentencing range of twenty-one to twenly-seven months. He also suggests that he should be resentenced under subsection (b)(1) of 8 U.S.C. § 1326 (establishing maximum ten-year sentence for illegal reentry in case of alien whose removal was subsequent to conviction for felony other than aggravated felony), rather than subsection (b)(2) (providing maximum twenty-year sentence where removal followed aggravated felony conviction). We leave these issues for the district court on remand.
