Anderson Silva shattered his leg on a kick. A YT video is linked in the article. If you don't want to watch it, then don't click on it.
I never was a fan of Silva 'clowning' people, or White for coaxing Silva out of 'retirement', but that's just a shame. Guys usually don't go out on top, but that's a hell of a way to lose. It's too bad that Weidman probably won't yet get the respect he deserves. He was beating Silva pretty bad.
