DENVER - Longtime Denver radio talk show host Peter Boyles is still off the air after last week's suspension following a "heated physical exchange" with his producer.
Jon Caldera of the Independence Institute has been filling in on Boyles' morning talk show on KHOW radio since the May 23 incident. Caldera will be on the air again Wednesday morning. Sources say they have fill-in guests for Boyle's show through Friday.
Last week, 9NEWS reported how coworkers of Boyle observed red marks on producer Greg Hollenback's neck within the minutes of the argument, which happened during Thursday morning's broadcast of the Peter Boyles Show. Hollenback is known on-air as the "Sheik of Cherry Creek".
Boyles and Hollenback have worked together for about two decades. The sources wished to remain anonymous because they were not authorized to speak on the matter.
"Everyone here is disappointed and devastated," one employee told 9NEWS.
It's unclear exactly what led to the exchange. There are no police records of the incident at this time.
ClearChannel issued the following statement Thursday: "This is a personnel matter. Out of respect for our employees, we are not commenting at this time."
