"Why you going to walk up on me like that?" Griffin reportedly asked O'Neal. "Leave that ... on the court. Leave that ... on the court."
O'Neal snarled, shook Griffin's hand and walked away.
"Man, I'm a monster off the court," O'Neal said, turning away.
Seth Burton, the Clippers' vice president of communications, tried to intervene, but O'Neal still got into Griffin's face.
The Clippers told the Times they will report the incident to the NBA.
