BASKIN, Judge.
We affirm defendant Johnson’s convictions for robbery and grand-theft second degree of a bicycle entered following his violation of his probation. In accordance with State v. Hegstrom, 401 So.2d 1343 (Fla.1981), however, we vacate the sentence imposed for grand theft. We note that defendant’s multiple convictions preclude a sentence under the Youthful Offender Act, Chapter 958. State v. Goodson, 403 So.2d 1337 (Fla.1981).
Affirmed as modified.
