INDIANAPOLIS (AP) — Prosecutors have postponed an initial court appearance for Indianapolis Colts owner Jim Irsay indefinitely.

Irsay had been scheduled to go to court Wednesday following his March 16 arrest on drug-related charges, but the Hamilton County Prosecutor's Office issued a statement Tuesday saying the hearing was postponed “unless or until” formal charges are filed against him.

Prosecutors and Irsay's family say he is undergoing treatment at a facility outside of Indiana.

The 54-year-old Irsay was arrested near his home in suburban Carmel on preliminary charges of misdemeanor driving while intoxicated and four felony counts of possession of a controlled substance. Police say they found multiple prescription drugs in his vehicle.

Hamilton County Chief Deputy Prosecutor Andre Miksha says prosecutors aren't bound by preliminary booking charges.
