A man who alleges Broncos wide receiver David Kircus punched him outside his house earlier this year testified Thursday that he never saw the punch that felled him. "It was just a pop and flash and then I realized I was on the ground on my hands and knees," Jeff Krieger said during Kircus' preliminary hearing.  After the testimony, a judge determined there was probable cause to continue toward trial. Kircus will be arraigned next month.

After Schote got upset with Kircus, Krieger said he tried to get the player to leave peacefully. After trying several times, he escorted Kircus out of his home through the garage. Krieger testified that as the two walked, Kircus said, "Once we get to the end of the driveway, you're not protected anymore."
