The Celtics dealt Kristaps Porzingis to the Hawks in a trade that slimmed their payroll, but they still had to say farewell to one of their starters.

Boston Celtics president of basketball operations Brad Stevens revealed what happened when he called Kristaps Porzingis to tell him he had been traded.

Kristaps Porzingis' exit from the Boston Celtics was made official on Monday, July 7. The veteran big man was sent to the Atlanta Hawks as part of a three-team trade that also included the Brooklyn Nets.
