The Boston Celtics were already facing what seems like a must-win scenario in Game 4 against the Milwaukee Bucks, trailing 2-1 in the series.
That challenge just got a lot tougher.
Starting center Robert Williams III received surgery to repair a partially torn meniscus in his left knee prior to the start of the playoffs, forcing him to miss the final seven games of the regular season and the first two games of the postseason.

Robert Williams (left knee soreness) - OUT
Williams wasn't originally on the injury report, but head coach Ime Udoka said some soreness "fired up" in the morning prior to Game 4. He mentioned Williams has been sore, at times, but it was "just a little worse today," per The Athletic's Jay King.
As mentioned above, this is the same knee that caused Williams to miss the final seven games of the regular season and the first two games of the playoffs after receiving surgery to repair a partially torn meniscus.
Williams eased his way back into the rotation, only playing 15 minutes in each of his first two games upon his return in Game 3 against the Brooklyn Nets.
He was inserted back into the starting lineup to begin the series against the Bucks, averaging 8.7 points, 5.7 rebounds, 2.7 blocks and 1.0 steals in 23.7 minutes per game.

Williams has been a key piece in the Celtics' playoff push, knocking down 48.6 percent of his 3s while playing physical defense on the likes of Kevin Durant and Giannis Antetokounmpo.
As mentioned in the tweet above, reserve center Daniel Theis will also receive an uptick in playing time, as he did in the first round when Williams was out. Against the Nets, Theis averaged 8.5 points and 6.5 rebounds in 22.0 minutes per game.
