Teams in touch with the Knicks say New York has not ruled out the possibility of trading Porzingis, though one club said it came away with the impression that the price tag for the star forward was extremely high.
The Vertical first reported that team president Phil Jackson was taking calls on potential Porzingis deals.
ESPN reported in April that several teams had called the Knicks about potential trades involving Porzingis. The group of teams to call the Knicks in recent days, per sources, includes several with 2017 NBA draft picks higher than New York's.
The New York Daily News reported later Tuesday that the Boston Celtics, who have the No. 3 overall pick, are among the teams that have reached out to the Knicks. New York has the eighth pick in Thursday's draft.
Porzingis skipped exit meetings with Jackson and general manager Steve Mills in April because of frustration over the dysfunction and drama surrounding the Knicks, who finished with a 31-51 record. Neither the organization's front office nor coach Jeff Hornacek has been in touch with Porzingis since he missed the exit meeting, per sources. Hornacek said last month that he reached out to Porzingis but indicated that Porzingis did not respond.
Porzingis' brother, Janis -- who also works for Andy Miller, Porzingis' primary agent -- reiterated Tuesday that Porzingis loves New York and wants to win there.
"Despite how the Knicks are treating their players, Kris wants to stay in New York," Janis Porzingis said. "He loves the city and he loves the fans and he wants to win with this team. If he's going to be traded, he's going to play out his contact and decide his future on his own."
Jackson was asked during his season-ending news conference in April if any personnel move, including a trade of Porzingis, is "off the table" this offseason.
"Everything has got to be possible, and we have to make sure that if people have something to say, we listen to it, we examine it," Jackson said before complimenting Porzingis for his development this season.
Porzingis, 21, averaged 18.1 points, 7.2 rebounds and 2.0 blocks in 2016-17, his second NBA season.
Jackson met with Arizona forward Lauri Markkanen recently, sources confirmed to ESPN. Markkanen plays the same position as Porzingis. The Knicks also have shown interest in Kansas' Josh Jackson, sources told ESPN's Ramona Shelburne. New York likely would have to move up significantly to select Jackson, who is widely considered a top-five pick.
Phil Jackson's meeting with Markkanen was first reported by The Vertical.
A June 19 story incorrectly stated, via sources, that there had been no contact between Kristaps Porzingis and the Knicks since Porzingis skipped his exit meeting with the team in April. Team sources now say there has been minimal contact between members of the organization and Porzingis, though "not much at all," according to one team source.
