Irsay's trial had been scheduled for next week, but Hamilton County court records show it's been rescheduled for Oct. 30.
Irsay was arrested March 16 near his home in the Indianapolis suburb of Carmel after he was spotted driving slowly, stopping in the roadway and failing to use a turn signal. Officers said he had trouble reciting the alphabet and failed other field sobriety tests.
A police report said various prescription drugs were found in his vehicle, along with more than $29,000 in cash.
Irsay was charged with driving while intoxicated and driving with a Schedule I or II controlled substance in his body.
