Joe Borgia, NBA Senior Vice President of Replay & Referee Operations, confirmed that Giannis' Euro Step was NOT a travel:

Celtics can't get a shot off after the Hornets almost steal the ball back, sending the game to OT

Donovan Mitchell got a makeup call on the very next play after that egregious travel by Harden

Lebron with a nice skip pass to Dorian Finney-Smith who drives for a reverse layup

Giannis full steam ahead and gets his 22 point of the half
