The Milwaukee Bucks have just booked their spot in the second round in what is going to be a mouth-watering matchup against the Boston Celtics. The preparations will now begin for the Bucks but unfortunately for them, it sounds like they might have to navigate the conference semis without All-Star swingman Khris Middleton.

According to NBA insider Adrian Wojnarowski, Middleton’s MCL sprain has now put him in danger of missing the Bucks’ second-round series against Boston:

“He’ll get that re-evaluation at the 14-day/two-week point next week,” Woj said, “but I’m told that injury is expected to keep him out longer than that…  [The Bucks] may have to get through another series — a conference semifinal — before they may have the opportunity to get Khris Middleton back in this season.”

That’s a tough blow for the Bucks. According to Woj, Middleton will get re-evaluated in a couple of weeks’ time. However, he is not expected to return immediately after that re-evaluation. This only means that the injury is serious and that the Bucks star could be on the shelf for an extended period.

Giannis Antetokounmpo has been an absolute beast for the Bucks and it sounds like he’ll be without his partner in crime in the East semis against the Celtics.
