The Boston Celtics defeated the Philadelphia 76ers 95-89 in their Summer League debut, though it wasn't all smooth sailing for the young team.
They lost rookie Robert Williams to a knee contusion, and it was a close game throughout, the Celtics pulling away for a win in the final minutes of the fourth to secure the win despite Williams missing much of the game.
Big performances from Semi Ojeleye (16 points) Guerschon Yabusele (16 points, 7 boards) and Jabari Bird (14 points, 8 boards) were the reason Boston came away victorious.
