Milwaukee Bucks star Khris Middleton missed Wednesday's win over the Indiana Pacers, however the reigning NBA champions are hopeful his knee injury is a short-term problem after positive MRI results.

Middleton had warmed up prior to the 114-99 victory, but did not take his place in the side missing seven players, including superstar Giannis Antetokounmpo – who entered COVID-19 protocols on Tuesday.

Bucks small forward Middleton had hyperextended his left knee in Monday's 117-103 loss to the Boston Celtics and was forced out of the contest.

Milwaukee head coach Mike Budenholzer confirmed Middleton had undergone an MRI which offered reason for encouragement.

"I think we consider everything very fortunate," Budenholzer told reporters. "This should be very minimal and short. We'll see how he feels [Thursday] and going into the game Friday, I think we'll be hopeful."

Antetokounmpo joined Wes Matthews and Donte DiVincenzo in being unavailable due to entering league protocols.

To clear protocols, a player must be out for a minimum of 10 days or return two negative PCR tests at least 24 hours apart.

"We'll follow all the guidelines that the league has laid out," Budenholzer said. "Hope he's just healthy and taking care of himself."
