Horford will not play Wednesday against the Nets due to a left big toe sprain, Marc D'Amico of the Celtics' official site reports.
Though Horford is being listed with an injury, he's essentially getting Wednesday's contest off for rest purposes since the Celtics are playing on the second leg of this back-to-back set. With Horford sidelined, Neemias Queta is likely to pick up the bulk of the center minutes with Luke Kornet stepping up as well.
