Milwaukee Bucks forward Bobby Portis has suffered an MCL sprain in his right knee, sources told ESPN's Adrian Wojnarowski on Wednesday.

The Bucks are still working through a timeline on Portis' return, sources said.

Portis suffered the same injury in 2018-19 with the Chicago Bulls and missed nearly seven weeks.

He had left Monday's win over the Detroit Pistons early in the fourth quarter after grabbing a 10th rebound to record his 29th double-double of the season. He had already been ruled out for Wednesday's game against the Denver Nuggets.
