SCOTTSDALE, Ariz. (AP) — Charles Barkley will serve time in jail after pleading guilty to charges of driving drunk.

According to Scottsdale court records, the 45-year-old former NBA star pleaded guilty Monday to two misdemeanor charges related to the same drunken driving arrest.

Barkley, who works as a TV analyst, is set to begin a five-day jail sentence on March 21. The Hall of Famer must pay more than $2,000 in fines and attend an alcohol treatment program. Under Arizona law, he'll also be forced to install an ignition interlock device on his vehicles.

His attorney wasn't immediately available for comment.

Barkley was stopped by police Dec. 31 shortly after leaving a Scottsdale nightclub. He was arrested after failing a field sobriety test. He had a blood-alcohol level of .149 percent, nearly twice the legal limit of .08 percent in Arizona when he was pulled over.

After a six-week leave of absence, Barkley resumed his studio analyst role for TNT last week.

"This is just my bad, no excuses," Barkley said in an interview with TNT colleague Ernie Johnson posted on NBA.com before he returned to work.

"I think that a DUI is unacceptable," he added. "That can't happen and I've got to challenge other people, not just celebrities or jocks. You have to really think before getting behind the wheel after you've been drinking."

Barkley conceded at the time he could face jail time.

"I think it's going to be good for me, to be honest. I need to make sure drinking is not a problem for me," he said. "I just want some professionals to talk to me about it."

If they tell him to stop drinking, "then I'll have to stop drinking," he said.

Asked if he could do that, he replied, "I feel I can do anything that I put my mind to."
