NEWARK, N.J. (AP) — Retired NBA star Jayson Williams will not be in a New Jersey courtroom Friday to enter a plea in the 2002 shooting death of a driver.

A judge has indefinitely delayed a hearing in Somerville in which Williams was expected to plead guilty. No reason was given.

A person with knowledge of the case told The Associated Press on Thursday that Williams would plead guilty to aggravated assault. The person wasn't authorized to talk about the case and spoke on the condition of anonymity.

Williams has been awaiting a second trial for reckless manslaughter. He was acquitted of aggravated manslaughter in 2004 but convicted of covering up the shooting at his central New Jersey mansion.
