Emergency services were called to the popular Sydney entertainment precinct of Enmore Rd, Newtown on January 22 where they treated the officers, including a 25-year-old who was unresponsive.
An off-duty nurse gave him CPR until paramedics arrived and he was taken to hospital.
Both police have since been released from care.
Koby Weaver, 20, and Danai Deneiderhavsein, 18, faced Downing Centre Local Court last Friday on charges relating to the incident but neither received bail.
Police confirmed on Wednesday that a 22-year-old man was also arrested in Enmore on Tuesday afternoon.
He has been charged with inflicting grievous bodily harm with intent and assault occasioning actual bodily harm in the company of others.
Police did not issue him bail and he will face the Newtown Local Court on Wednesday.
Weaver was charged with causing grievous bodily harm with intent, while Deneiderhavsein was charged with two counts of assault occasioning actual bodily harm in company.
A court was last week shown a brief phone-camera clip said to capture part of the alleged confrontation.
