Glass chinned chicken dancers go down. They don't do a dance and then recover. Check Judah, Khan and Jones Jr
He took it though from a pretty good puncher. I don't think he was that badly hurt, he was definitely stunned but he kept punching back and recovered well. I wouldn't say it's glass just yet. If anything he showed a decent enough chin, though clearly not iron, if that had been Price that got hit he would have definitely gone down and maybe not even made it out of round 2.
