Miami Heat teammates LeBron James and
Chalmers had a turnover, missed a three-pointer and committed two fouls during a two-minute span in the third quarter.
After James and Chalmers had a misunderstanding on defense that freed up Paul George to make a three-pointer with 7:56 left in the third, James let his frustration get the better of him.
During a timeout, James leaped out of of his seat, appearing as though he were going to attack Chalmers. He was restrained by teammates.
James later apologized over Twitter.
