The Boston Celtics will have their frontcourt depth tested Monday night as they face the Minnesota Timberwolves.
Jared Sullinger and Amir Johnson have been ruled out for tonight's game, according to Adam Himmelsbach of the Boston Globe.
Sullinger has been the starting center for the majority of Boston's games this season, averaging 10.0 points and 9.5 rebounds and posting a player efficiency rating of 17.20.
Johnson has been one of the most underrated signings of the offseason, with the 28-year-old leading the team in net rating (plus-5.3) and blocks per game (1.3).
David Lee and Kelly Olynyk are candidates to start in Johnson and Sullinger's absence.
