James made the gesture after making a shot late in Los Angeles' 124-116 overtime victory in Indiana on Wednesday night.
He had missed a loss at New York a night earlier after he was suspended one game for hitting Detroit center Isaiah Stewart in the face and drawing blood last Sunday. He used profanity in an interview with ESPN after the victory in Indiana when discussing the suspension.
Also Friday, the NBA fined Portland's Robert Covington $15,000 for throwing his face mask at a referee Wednesday. He was given a technical foul and ejected for that action with 49 seconds left in the second quarter of the Trail Blazers' 125-121 loss at Sacramento.
