Forty-two-year-old George Villanueva also was convicted of criminal contempt this month. He was acquitted of a more serious murder charge.
Villanueva said at his sentencing Wednesday that he is innocent. He said if he'd known the officer was going to fall, he would have helped him.
Officer Alain Schaberger was responding to a domestic violence call made by Villanueva's girlfriend. He toppled 9 feet from a Brooklyn stoop in 2011, breaking his neck.
The prison term also includes a charge for violating the order of protection that touched off the incident.
