Could Ja Morant slide to the Knicks at No. 3 now that he’s undergoing minor knee surgery?

Morant will undergo an arthroscopic procedure on his right knee to remove loose fragments of bone or cartilage and will be fully recovered in 3-4 weeks, according to ESPN.

The Post reported Memphis was leaning toward the Murray State point guard after the lottery reveal with the No. 2 pick, with Duke swingman RJ Barrett falling to 3. According to a source at the combine, however, the Knicks never thought Morant was a shoo-in for Memphis.

Now ESPN is reporting Memphis is loosening on its “locked-in’’ stance on Morant. The Grizzlies have requested a workout for Barrett, but so far have not gotten a commitment.

The Post reported at the combine Barrett prefers to drop to third to the Knicks or fourth to the Lakers.

The Post has also reported Morant has fans in the Knicks organization and had him slightly higher on their board at the time of the combine. In fact, the Knicks considered Morant a first-round pick in the 2018 draft after his modest freshman year at Murray State, seeing his potential.

Morant stayed another season, and his bust-out performance as a sophomore vaulted him into high-lottery status, proving to be a terrific passer and improved perimeter shooter. The Knicks interviewed Morant at the Chicago combine in May. Defense is Morant’s issue.

The Knicks, meanwhile, are scheduled to work out Barrett on June 10, though the situation is fluid. Barrett, whose offensive game is still incomplete in some scouts’ eyes, staged his pro day at UCLA last Tuesday but did not do drills. It was attended only by Knicks West Coast scout Mike Smith and scouting director Kristian Petesic.

Morant claimed he knew nothing of Memphis being a guarantee — which ESPN reported the day after the lottery.

“I haven’t seen it. [Memphis] didn’t tell me that,” Morant told The Post two weeks ago at the NBA store. “I mean, we’ll find out where I go on June 20.”

The surgery, considered minor, “allows doctors to view the knee joint without making a large incision (cut) through the skin and other soft tissues,” according to OrthoInfo.org.

Morant suffered a knee-to-knee collision against Florida State during the NCAA Tournament — though, after a brief pause, he stayed in and put up 28 points in a loss. It’s unclear if this instance is related to the upcoming procedure.

Barrett is well-liked by the Grizzles. According to a source, Grizzlies draft consultant Glen Grunwald, who is the CEO of Canada Basketball, is a big fan of the 6-foot-7 Canadian.

The idea of Memphis drafting Morant would further motivate them to trade point guard Mike Conley, but that’s no easy task because of his massive contract.

Morant and Barrett join slam-dunk No. 1 pick Zion Williamson at the top of the draft, followed by everyone else.
