PER CURIAM: Melvin Lamont Timmons appeals his convictions for criminal sexual conduct in the second degree, kidnapping, armed robbery and possession of a pistol by a person under twenty-one. Timmons contends his guilty plea was not knowing and voluntary. We dismiss his appeal pursuant to Rule 220(b), SCACR, and the following authorities: State v. McKinney, 278 S.C. 107, 108, 292 S.E.2d 598, 599 (1982) (stating absent a timely objection during guilty plea, the unknowing and involuntary nature of a plea can be attacked only through the avenue of post-conviction relief); State v. Barton, 325 S.C. 522, 530 n.6, 481 S.E.2d 439, 443 n.6 (Ct. App. 1997) (stating any challenge to the knowing and voluntary nature of a guilty plea can be raised only in a petition for post-conviction relief).
HEARN, C.J., and SHORT and KONDUROS, JJ., concur.
 We decide this case without oral argument pursuant to Rule 215, SCACR.
