INDIANAPOLIS (AP) — The family of Colts owner Jim Irsay said Tuesday that he has placed himself in a treatment facility after police found multiple prescription drugs in his vehicle during a traffic stop.

The 54-year-old Irsay, who acknowledged a painkiller dependency more than a decade ago, faces preliminary charges of misdemeanor driving while intoxicated and four felony counts of possession of a controlled substance. He was arrested near his home in suburban Carmel late Sunday and released the next day.

If Irsay is charged and convicted on the felony counts, he could face six months to three years in prison on each count.
