At about 8:15 p.m., the officer spotted a known parolee with an active arrest warrant for narcotics who was driving near South 11th and East Santa Clara streets, San Jose police Sgt Jason Dwyer said.
The officer initiated a pursuit into the 100 block of South 11th Street, where the suspect pulled over and fled on foot, Dwyer said.
The officer was taken to Regional Medical Center to be treated for a concussion and back pain, Dwyer said. He was later released.
A house-to-house search for the suspect yielded no results, and an investigation into his whereabouts is ongoing.
