A lawyer for firebrand attorney Michael Avenatti said Thursday that he plans to subpoena Nike ahead of his client’s upcoming extortion trial — but balked when asked if his sights were also set on the company-linked pro athletes.

“I’m going to issue a subpoena to Nike,” Avenatti lawyer Scott Srebnick told Manhattan federal court Judge Paul Gardephe on Thursday, adding he was looking for information regarding an alleged pay-to-play scheme targeting elite high school basketball players.

“It could be Nike employees, it could be others,” he continued, refusing to say whether any pro ball players would be called.

Avenatti is charged with extortion for allegedly shaking down Nike for $20 million while threatening to publicize an alleged pay-to-play scheme within the company — unless it hired him to conduct an internal investigation.

In a recent motions to dismiss the indictment, the 58-year-old’s defense team claimed a Nike employee signed off on payments to hoopsters Romeo Langford and Zion Williamson, of the Boston Celtics and New Orleans Pelicans, when the duo were high-schoolers.

Srebnick asked that Gardephe allow him to serve Nike and Nike employees in a continued attempt to prove the misconduct Avenatti has alleged.

Srebnick said he’d already received more than 2,600 pages of Nike-related evidence from prosecutors. The attorney also said he expected the current trial date of Nov. 12 to be “optimistic,” as he expected a number of his targets to invoke their Fifth Amendment rights against self-incrimination.

Gardephe did not rule immediately on the request and instead asked both sides to submit their motions in writing.

Avenatti — who first rose to national attention while representing porn star Stormy Daniels in her lawsuit against President Trump and Michael Cohen — declined to speak following the hearing.

He has since parted ways with Daniels, whose real name is Stephanie Clifford, and is now facing separate indictments in New York and California for fleecing her and other clients out of more than a million dollars.
