Boston Celtics GM Danny Ainge has made it official...the Celtics #1 pick in Thursday's draft has been traded to Philadelphia.

In exchange, the C's get Philly's #3 pick Thursday night and another future first round pick.

That pick will be a LA Lakers draft pick (owned by the 76ers) in 2018 if it falls somewhere between #2 thru #5.

If not that one, the C's get the 2019 first pick of the 76ers or the Sacramento pick (owned by the 76ers), which ever one is more favorable to Boston.

NBA insiders now think the Celtics will target either Josh Jackson from Kansas or Jayson Tatum from Duke.

This story will be updated.
