Kristaps Porzingis fully participated in the Boston Celtics' practice on Saturday, according to Joe Mazzulla.

Mazzulla did not reveal whether he would insert Porzingis into the starting lineup for Game 1.

"When KP's at his best, he's been tremendous for us. We expect that from him, and we know he'll give that to us. And as far as everything else, just what goes into winning is the most important thing.

"What gives us the best chance to win each particular game, each particular possession and each particular matchup," said Mazzulla.

Porzingis has missed the last 10 playoff games due to a calf strain.

Game 1 of the NBA Finals starts on June 6.
