ESPN’s Marc Stein and Zach Lowe initially reported the story.
The package will reportedly include the Celtics’ No. 1 pick and the Sixers’ No. 3 selection, according to Stein and Adrian Wojnarowski of Yahoo! Sports.
Should Markelle Fultz’s medical come through without any issues, the trade will then be completed.
The Celtics were expected to take Fultz with the first-overall pick if they held onto it.
