I was watching it live on TV. Perhaps some fans were being gracious, but most weren't. I've never seen or heard anything like it before or since.
At first the fans were cheering him staying down(you have to understand how much people hated Irvin, who was a drugged up thug then) because it looked like Michael Zordich drilled him (he didn't). Then people saw how serious it was and got silent. Then Deion started his foolishness and people booed. When Irvin went off on a stetcher there was cheering when people knew how serious it was.
