Golden State Warriors forward Draymond Green could face a stiff fine from the NBA after a run-in with female referee Lauren Holtkamp during the Oklahoma City Thunder's statement win at Oracle Arena. After Thunder forward Jerami Grant collided with Green on a drive early in the second quarter of Tuesday's game — resulting in a turnover and a Warriors layup on the other end — the reigning Defensive Player of the Year came up bleeding from his mouth and gave Holtkamp an earful. No technical foul was issued.
