Middleton was a late scratch for Wednesday's game against the Detroit Pistons due to personal reasons, but was present at Friday's team shootaround.
Last Saturday, Middleton played just 18 minutes in the Bucks' 136-134 overtime loss to the New York Knicks. The seven-year veteran was benched by head coach Mike Budenholzer for a lack of effort.
In 22 games played, Middleton is averaging 18.5 points, 5.5 boards, and four assists per contest.
The Bucks are currently second in the Eastern Conference with a 16-7 record.
