All I know is that there was an alleged 15,800 sellout (though Puroresufan.com says it was more like 10,000) at Nippon Budokan, and the match was about 20:09 long. They say it was a pretty slow match, and Hashimoto won it with a brainbuster.
I don't know how to linkify, but check out Puroresufan.com, they have some info on the show.
I'm sure what Tazz meant was that Sasuke kicked stiff, not that Sasuke had literally caved in his skull with kicks during a match. As to whether that's true, if Tazz said it, sure, there's probably some credibility to that.
