An MRI scan on Monday revealed the rupture and further evaluation on Monday will help provide a timeline for a possible return, sources said. Boston climbed to No. 1 in the Eastern Conference on Sunday and the 24-year-old Williams was a huge part of a dominant defense in the league. Williams was injured in the 134-112 victory over the Minnesota Timberwolves on Sunday – the Celtics’ 24th win in 28 games.

Williams is No. 1 among 169 players in the league who have defended 500 more shots as the nearest defender per second Spectrum watch. Only Williams has opponents below 40% shots. Williams – who signed a new four-year extension of $ 54 million out of season – averaged 10 points, 9.6 rebounds and 2.2 blocks. He has shot 73% from the floor.
