Khris Middleton (left MCL) has a Grade 2 sprain according to Shams Charania and is expected to miss the entire second-round series vs. Boston.
Shams adds that a potential return in the Eastern Conference Finals is in jeopardy too. This is a tough blow for the Bucks against an elite Boston defense, and they will need guys like Grayson Allen and Pat Connaughton to step up like they did vs. Chicago.
