The NYPD sergeant who was in charge of the scene when Eric Garner died will be put on administrative trial by the end of the year, according to officials.

“At this point, there’s one more trial, and it will also again be a public trial held by the NYPD for one of the sergeants involved,’’ Mayor Bill De Blasio told MSNBC on Tuesday, referring to Sgt. Kizzy Adonis.

“That will be concluded this year. That will end all the disciplinary issues being handled by the NYPD.”

A day earlier, one of the officers under Adonis’ watch, Daniel Pantaleo, was fired by Police Commissioner James O’Neill over his bust gone horribly awry on Staten Island in July 2014.

An administrative-trial judge had recommended Pantaleo’s firing, saying his use of a chokehold on the 44-year-old dad during an arrest for peddling loose cigarettes was at first “acceptable’’ but then should have been eased during the takedown.

Garner was caught on video repeating “I can’t breathe’’ during the incident.

Garner’s family has asked for more heads to roll in the case, including Adonis’.

Asked what was taking so long for the sergeant’s case to head to an internal trial, O’Neill told reporters Monday, “It will be soon.”

“It’ll be this year, definitely this year,” he said.

“It’s a disciplinary case. We have to make sure that we look at all the facts. You have to make sure we have conducted thorough investigation. And then we move forward.”

Adonis did not respond to a request for comment.
