SAN ANTONIO -- A judge has dismissed charges against former San Antonio Spurs player Alvin Robertson related to an alleged underage sex ring.

The San Antonio Express-News reports that state District Judge Jefferson Moore on Monday ruled that Robertson, who played with the Spurs from 1984 to '89, was innocent of charges of sexual assault of a child, trafficking an underage child for purposes of sex and forcing a sexual performance by a child.

Brent De La Paz, Robertson's attorney, said, "There was no ring. There were no girls. There was one girl who made up the whole story."

Robertson said Monday he was relieved.

"It's been a nightmare. I am glad to have it behind me."
