Injured Kristaps Porzingis on track for return as Celtics prepare for NBA Finals against Mavericks

Whether injured Celtics center Kristaps Porzingis will be ready in time for the start of the NBA Finals this week is still to be determined. The 7-footer hasn’t appeared in a game since sustaining a strained left calf in Game 4 of Boston’s first-round playoff series against Miami on April 29. Celtics coach Joe Mazzulla has refrained from making predictions on when he expects Porzingis to be available.
