Defense attorney John Tompkins said Friday that Williams plans to enter a plea agreement on the misdemeanor charge by Oct. 1, the day before the Pacers open training camp.

Williams did not attend Friday's initial court hearing, but later apologized for his actions and said he would accept a three-game suspension imposed by the team.

On Thursday, prosecutors decided not to file marijuana possession charges against Williams.

Williams, 21, was jailed for several hours on an initial charge of marijuana possession after police said they found a marijuana cigarette burning inside his SUV after it was pulled over early Tuesday for changing lanes without signaling.

A passenger faces a misdemeanor count of marijuana possession.

"In this case, the passenger said it belonged to him," said David Wyser, the chief trial deputy for the Marion County prosecutor's office.

Williams apologized to team owners Melvin and Herb Simon, the front office staff, his teammates and Pacers fans.

Williams told reporters he would be more careful about who he is with.

"Before I would just get into the car with anybody, but now I'm going to ask whoever gets in the car with me what they have and what they're doing," he said. "Me being a professional ballplayer, I have to surround myself with better people."

The 6-foot-9 Williams, who was the Pacers' first-round draft pick last year from Memphis, averaged 3.9 points and 1.8 rebounds in 46 games last season.

Tompkins said Williams has never held an Indiana driver's license. He said he was not sure whether Williams has held a driver's license in any other state and had requested records from Tennessee and South Carolina to determine if he had ever held a license in those states.

Pacers president Larry Bird said Friday he believed Williams was remorseful and embarrassed by his arrest.
