The NBA may have lost another top superstar due to injury.
On Friday, Jimmy Butler appeared to have suffered a non-contact injury to his right knee. He left the game against the Houston Rockets unable to put any pressure on his right leg and needed assistance getting back to the locker room.
Here's a video of the incident:
Coach Tom Thibodeau said that Butler will have an MRI when the team returns to Minnesota on Saturday.
Butler drew a lot of headlines last weekend after not playing in the NBA All-Star Game in Los Angeles.
Entering Friday, Butler led the league with 37.3 minutes played per game.
