Khris Middleton left the Milwaukee Bucks' 105-92 win over the Chicago Bulls due to right knee soreness in the first quarter and did not return to the game.

Mike Budenholzer described the injury as a re-aggravation of the knee soreness that bothered Middleton throughout the season.

Budenholzer said he was unsure of Middleton's status for the final two games of the regular season.

"We'll learn more going forward. So, I couldn't say tonight," said Budenholzer. 

The team is also likely to be without Grayson Allen for the rest of the regular season. 

The Bucks clinched the No. 1 seed in the Eastern Conference on Wednesday.
