Was Hopkins the first fighter to attempt a piggyback?

It happened many times. Many times a fighter used his weight to push another fighter down, many times the dude being pushed down lifted up the fighter doing it. Fighters have also pushed opponents out of the ring or down to the canvas. It's not too often it results in an injury. But it happens!

I wonder if Hopkins is also the only fighter to be pushed out of the ring by a referee?
