Did Mike Tyson knockout a referee?

No, he was finishing Lou Savarse, and the referred tried stopping it and got in between them, and Tyson clipped the referee with his arm, more less pushing the reference down.

He was not hurt or unconscious, and Tyson won.

Nothing close to a knock out, I've heard this urban myth myself.
