Kristaps Porzingis can't play basketball right now ... but that doesn't mean he ain't havin' fun -- 'cause the Knicks superstar just hit up an NYC party with Ivan Drago!!!
Dolph Lundgren was out at Mr. Chow Tribeca -- celebrating the upcoming release of 'Creed 2' -- so The Unicorn put his ACL rehab on hold and popped by to to join the party.
Why?? We're told Kristaps -- whose nickname used to be "Young Drago" -- is a HUGE fan of the 'Rocky' villain, and always wanted to meet him.
The first interaction between the two at the Haute Living and Zenith Watches bash was pretty great .
