jokichik is a center and has played in all but three games this season.
He averages 15.8 points and 6.4 rebounds per game, and he has become a consistent part of a team that has lost the final four games of the season and will face the Cavaliers on Wednesday night.
The Celtics are still trying to figure out whether to make Jokichic the starting center after he went down with a calf strain and will need a change-up if they hope to stay competitive in the East.
They signed Jokis younger brother, Deon, last month.
Boston has lost five of its last six games, including three in a row.
The Celtics lost a two-game sweep by the Lakers in Los Angeles.
