The Mavs owner forcefully shut down persistent rumors that Dallas is looking to move the 25-year-old ... despite only being in the 2nd year of a 5-year $158 million contract he signed in 2019.
There have been rumblings about the Mavs looking for a trade partner for the past month -- including an SNY report that Dallas has reached out to the Golden State Warriors to see if they were interested in a deal.
Cuban had denied the rumors back in February -- but the rumblings continued -- which led to Cuban slamming the door shut on a possible KP move during Tuesday's appearance on "Live with Kelly & Ryan."
"We're not trading KP," Cuban said ... "KP's a star."
As Ryan Seacrest continued to probe, Cuban doubled down -- "It's not gonna happen, Ryan. You heard it here first. Definitely not gonna happen."
Porzingis missed the first 3 weeks of the NBA season while recovering from knee surgery -- and missed another 2 weeks last month with a back injury.
Despite the hiccups, KP is still a monster when he's on the court -- averaging 20.8 points and 8.4 rebounds per game.
The Mavs are currently in 8th place in the Western Conference -- and clearly Cuban is hoping KP will keep them in the playoff hunt.
... at least, for now.
