Kristaps Porzingis of the Boston Celtics remains questionable for Game 5 of the NBA Finals against the Dallas Mavericks due to a left posterior tibialis dislocation, a rare tendon injury. Despite being listed as available for Game 4, Porzingis did not play, as the team chose not to risk aggravating his injury. Celtics coach Joe Mazzulla indicated that Porzingis would only play under specific circumstances and acknowledged that he is 'not quite there' yet. Porzingis has been trying to recover and was seen practicing, but his participation will depend on his pain tolerance and medical clearance. The Celtics, leading the series 3-1, hope to clinch their 18th championship, potentially without their star center. If Porzingis is unable to play, Al Horford and Xavier Tillman are expected to fill in.
