Rockets owner fined $100K for confronting official during playoff game

Houston Rockets owner Leslie Alexander has been fined $100,000 by the NBA for leaving his courtside seat to confront an official during Tuesday's game-five win against the Oklahoma City Thunder.

The NBA handed down the punishment on Wednesday, following Houston's 105-99 Western Conference first-round series-clinching victory. 

Apparently upset over a no-call, Alexander took it upon himself to complain to referee Bill Kennedy in the final seconds of the first quarter.

Kennedy was watching the court while play was going on when Alexander approached from behind and gave the official an earful for several seconds before walking away.

Alexander, 73, declined to discuss the matter during half-time. saying only he was "upset, really upset."

The NBA announced immediately afterward that it was conducting an investigation into the matter. The resulting fine is a stiff message from the league, which has come down hard in the past on public-facing criticism of its officiating from owners, coaches and players.

Dallas Mavericks owner Mark Cuban, never shy about vocalising his opinion on NBA referees, said he was fined $25,000 in January for postgame remarks about an official.
