Seeing Bavetta knocked down, Gan Guoyang approached to check on him.
When Hugh Evans arrived, Gan Guoyang said to Evans, "He committed a blocking foul."
Evans gave Gan Guoyang a look of disbelief and said, "Don't joke, Sonny, that hit was hard. We need to bring in the stretcher team."
Bavetta was indeed hit hard. The CBS television slow-motion replay showed that as Gan Guoyang collided with Bavetta, his elbow hit Bavetta's chin.
Just that hit alone, let alone a slim referee like Bavetta, even a regular center would have struggled to tolerate it.
But to say Gan Guoyang did it on purpose, it didn't look like it from his actions, because he raised his elbow to swing his arms to run. Upon closer inspection, there were no extra movements.
Instead, it was Bavetta. His positioning was too much to the inside, blocking the player's path of progress.
