Jimmy Butler suffered a knee injury during Wednesday night's 105-104 loss to the Philadelphia 76ers in the Play-In Tournament.
The veteran forward—who finished with 19 points, five assists, five steals and four rebounds but shot just 5-of-18 from the field—told reporters after the game that he would undergo an MRI on Thursday.
"It had me feeling that I couldn't do too much," he added of the injury.
