After an X-ray on James Johnson’s injured left shoulder returned negative, an MRI revealed a slight left AC sprain, the Heat announced Friday.
The 32-year-old power forward is doubtful to play in Saturday’s home game against the Pistons.
Johnson injured his left shoulder during Thursday’s loss to the 76ers and exited the game with 8:31 remaining in the second quarter. He did not return, finishing with three points and one rebound in seven minutes of action.
Johnson has played as a reserve in each of the Heat’s past six games. He’s made 33 starts at power forward this season.
