Boston center Kristaps Porzingis will be available to play in Game 4 against the host Dallas Mavericks on Friday night as the Celtics look to sweep the NBA Finals.

Celtics coach Joe Mazzulla told reporters before the game that Porzingis -- who is listed as questionable -- would only play if necessary and would "only be used in specific instances."
