LOUISVILLE, Ky. (WDRB) – Former University of Kentucky and NBA basketball player Rex Chapman began a 28-day substance-abuse treatment program at The Brook Hospital in Louisville on Monday, a source with knowledge of the situation said.

Chapman, who will be 47 Sunday, is determined to break a reliance on suboxone, a medication prescribed to help patients stop using opioid-based pain medication.

Chapman suffered multiple knee, ankle and thumb injuries over his 12-season, 666-game NBA career. He never played an entire 82-game schedule and retired from the Phoenix Suns, his fourth pro team, in 2000.

On Sept. 19, Chapman was arrested in Scottsdale, Ariz., a Phoenix suburb, for allegedly shoplifting $14,000 worth of merchandise from an Apple store and later selling the products at a pawn shop.

Police said that Chapman visited the store in north Scottsdale nine times between late May and early August this year. Chapman is alleged to have left the store without paying for the merchandise after appearing to use an iPhone app that is designed to enable customers to self-checkout.

Chapman faces nine counts of organized retail theft and five counts of trafficking in stolen property, all felonies, according to the Arizona Republic newspaper. Chapman posted a $14,000 bond.

Chapman was named Kentucky's Mr. Basketball in 1986. He played two seasons for coach Eddie Sutton at UK, averaging 17.6 points and scoring 1,073 points. He is the school's 50th all-time leading scorer.

According to basketball-reference.com, Chapman earned more than $22 million as an NBA player.
