Point-guard prospect Frank Ntilikina is scheduled to fly into Newark with his agents on Tuesday afternoon for the NBA draft, according to sources, despite his Strasbourg club forcing a winner-take-all Game 5 in the French league finals with an 84-78 victory over Chalon on Monday.

Game 5 is slated for Friday, the day after the draft, but Ntilikina may stay in New York. His French agent, Olivier Mazet, told The Post in recent days no decision has been made whether Ntilikina will make it back for Game 5 in France.

Mike Fratello, who is taping shows for NBA TV’s draft coverage, told The Post he thinks Ntilikina should stay with his French team.

“I don’t mean to be sarcastic, but what’s the necessity of him being here [at the draft]?’’ Fratello said. “He should stay with a bunch of guys that you’ve been in the trenches with and getting this far. If I was this young man, you’ve gone through all this with your team, to go back [to New York] to get a [team] hat and shake [commissioner Adam Silver’s] hand and have pictures taken.

“Stay there and help your team win and show what’s important to you — to put your blood, sweat and everything on the line to win a championship.’’

Ntilikina already has missed a chance to work out for NBA clubs, but is expected to take an NBA physical and measurements Tuesday afternoon, according to sources. The Knicks have shown great interest in the 18-year-old, 6-foot-5 point guard. The Post reported exclusively how new scout Makhtar Ndiaye spent nearly a month watching his games in France in April and May and that general manager Steve Mills and Clarence Gaines, Phil Jackson’s top adviser, also flew to France to watch Ntilikina at separate times.

Ntilikina told The Post last week he’d make a great fit with Kristaps Porzingis and in the triangle.

If the Knicks pass on Ntilikina at No. 8 and take someone such as Malik Monk or Donovan Mitchell, the Mavericks are expected to take the French prospect at No. 9. An ESPN report stated Dallas has hired his Strasbourg coach, Vincent Collet, as a summer-league coach and the Mavs are his preferred destination. Collet is the French national team’s coach.

The Post also reported Dallas owner Mark Cuban, GM Donnie Nelson and personnel director Tony Ronzone flew to Venice to meet with Ntilikina nine days ago after Strasbourg advanced to the finals.

The Mavericks were first on Ntilikina’s tail last season, when he barely played. Cuban got a tip from the point guard’s ex-Strasbourg teammate, Rodrigue Beaubois, a former Maverick.

The Mavericks could trade up to move past the Knicks into the seventh slot with a swap with Minnesota. Sources indicated the Timberwolves are interested in either Arizona big man Lauri Markkanen or N.C. State point guard Dennis Smith, and could get either if they fall to No. 9.

Ntilikina had a poor game Monday, going scoreless, and some scouts have reservations because of the meager numbers he has posted in the French league.

Mazet, Ntilikina’s French agent, told The Post the French league likely will look into never scheduling its finals so that they conflict with the NBA draft.
