In the profile of Dana White published by Esquire magazine, reporter Mike Sager asserts that Michael Jackson was a tremendous fan of the UFC. And he tells of how, one night, when taken by the uncontrollable urge to watch the fight show live, the star disguised himself as an old man and watched the spectacle from a wheel chair, in the front row.
Unfortunately, it is not likely anyone has this image. So, we are left with the video of the day MJ showed up at Pride, the now-extinct Japanese organization acquired by the UFC in 2007.
