The Boston Celtics may be one of the first teams to see highly-touted rookie Zion Williamson in a regulars-season NBA game. The New Orleans Pelicans' No. 1 overall pick participated in his first full practice with team Thursday as he recovers from a knee injury, per head coach Alvin Gentry. Gentry added Williamson won't play in the Pelicans' next two games (Friday against the Los Angeles Lakers and Saturday against the Sacramento Kings).
