During the pendency of this appeal, Daniel Kent Yantis completed the sentence imposed upon revocation of supervised release and was released from custody. Because no additional term of supervised release was imposed, this appeal is moot. See Spencer v. Kemna, 523 U.S. 1, 7, 118 S.Ct. 978, 140 L.Ed.2d 43 (1998); Bailey v. Southerland, 821 F.2d 277, 278 (5th Cir. *3311987). Accordingly, the appeal is DISMISSED as moot.
