Khris Middleton has a Grade 2 sprain in his MCL and is expected to miss the entirety of the Milwaukee Bucks' second round series against the Boston Celtics.

The typical recovery for a Grade 2 sprain could also mean Middleton misses the Eastern Conference Finals should the Bucks advance.

Middleton suffered the injury during Game 2 of the first round.

During last year's playoffs, Middleton averaged 23.6 points, 7.6 rebounds and 5.1 assists over 23 games as the Bucks won the championship.
