According to the AP, the 64-year-old singer was picked up by police at his home in Columbia, South Carolina on Thursday after Brown's family became concerned for the singer's health.
Brown was then reportedly admitted to an unnamed Columbia-area hospital, and his agent, Jeff Allen, told the AP, "He's had a problem with his back, and I don't want to say anything out of place, but he may have gotten addicted to painkillers for his pain. That's about all this boils down to, an addiction to painkillers."
Sheriff's deputies also reportedly seized a .30-caliber Winchester rifle and a .22-caliber handgun from the singer's home for safekeeping.
When asked about the incident, Brown's attorney, Albert "Buddy" Dallas, told the AP, "James is taking a long, well-deserved rest. He's been touring for the past five years."
In addition to his tour schedule, Brown also filmed an appearance for the upcoming sequel "Blues Brothers 2000."
