Last week 64-year old Andy McFarlan was severely injured in a road rage incident in Caledonia Township.

WZZM-13 reports that 18-year-old Christian Hillman of Ada is now facing assault with intent to commit great bodily harm charges.

Hillman is an ex-heavyweight  boxer who is claiming his actions were self-defense.

Police say the confrontation happened around 9p.m. Sept. 29 on Whitneyville Avenue between 60th and 68th Street.

Hillman says when McFarlan reached for his neck, he knocked him to the ground, punching and stomping him.

McFarlan's family says he remains in the hospital on a respirator and is unresponsive.
