The 66-year-old victim's wound wasn't considered life-threatening, responders said.
Rescuers carried him out of the woods on a stretcher in the Dunkerhook area of Saddle River County Park in Paramus a few miles from his home after concerned loved ones called police.
A waiting Paramus Medical Services rig took him to Hackensack University University Medical Center with a police escort and officers closing intersections along the route, witnesses said.
Paramus police, firefighters and EMS responded along with Bergen County sheriff's officers and Ridgewood police, among others.
Daily Voice is withholding the identity of the 26-year law enforcement veteran, who retired more than 15 years ago.
