LINCOLN, Neb. -- Nebraska freshman receiver Keyshawn Johnson Jr. has pleaded not guilty to possessing marijuana and drug paraphernalia.

Court records say the written pleas were filed Tuesday in Lancaster County Court in Lincoln. The records say an Aug. 7 hearing has been scheduled on Johnson's motion to receive pretrial diversion.

Johnson was ticketed last month after a resident director reported suspected drug use in a dormitory room.

The four-star recruit from Calabasas, California, had enrolled early and went through spring practice. He's since left school at the behest of his father, former NFL receiver Keyshawn Johnson. He says he wants his 19-year-old son to mature before a hoped-for return to Nebraska in January.
