Sources - Milwaukee Bucks' Khris Middleton to miss remainder of series vs. Chicago Bulls

Milwaukee Bucks star Khris Middleton will miss the rest of the opening-round playoff series against the Chicago Bulls due to a sprained medial collateral ligament in his left knee, sources told ESPN on Thursday.

Middleton will be re-evaluated in two weeks when a timeline on his possible return in these playoffs — if the Bucks advance — could become clearer, sources said.

Middleton underwent an MRI in Milwaukee on Thursday after suffering the injury in the fourth-quarter of the Bucks' Game 2 loss to the Bulls.

The Bucks head to Chicago on Friday for Game 3 with the series tied at 1-1.
