The actor explained that he welcomes getting back to work after the loss.

“Time, hopefully, will heal, and you try to get through it, but it’s just something… It’s a reality of life,” he said. “I think it’s important to get back and start reliving your life. Otherwise, you can go into a spiral.”

As previously reported on, an employee and a relative found Sage unresponsive in his Los Angeles home on July 13. When police arrived, they confirmed he was dead, Assistant Chief Coroner Ed Winter said at the time.

While the cause of death has yet to be determined, pending autopsy results, investigators have stated there were no signs of foul play or trauma.

Sage – an actor – starred with his father in the 1990 film “Rocky V.”
