His lawyer, Harvey Steinberg, said Kircus didn't know he needed to be present at Friday's hearing.
Kircus pleaded not guilty to a felony assault charge stemming from a fight at a party in suburban Denver in May 2007.
Friday's hearing was rescheduled for Oct. 17. His trial is scheduled to begin Oct. 20. If convicted, Kircus could be sentenced to 5 to 16 years in prison.
An Arapahoe County sheriff's report says Kircus hit a man in the eye after being escorted from a house. The incident put the 26-year-old victim in the hospital with multiple facial fractures.
