Jeffery McDaniel, federal prisoner # 08769-078, appeals the district court’s denial of his 28 U.S.C. § 2241 petition alleging that his constitutional rights were violated when the Bureau of Prisons (“BOP”) denied him a one-year sentence reduction, pursuant to 18 U.S.C. § 3621(e), after initially informing him that he was eligible for such a reduction.

McDaniel renews his argument that the denial of the one-year credit violated his due process rights and that promissory estoppel should prevent the BOP from reneging on its statement of eligibility. His claims fail because there is no protected liberty interest in early release under 18 U.S.C. § 3621(e). See Rublee v. Fleming, 160 F.3d 213, 216 (5th Cir. 1998); Venegas v. Henman, 126 F.3d 760, 765 (5th Cir. 1997) (“[t]he loss of the mere opportunity to be considered for discretionary early release is too speculative to constitute a deprivation of a constitutionally protected liberty interest”). Accordingly, the district court did not err in denying McDaniel’s petition, and its judgment is AFFIRMED.
