Several readers pointed out that the Undertaker seemingly collapsed after tonight's WWE SummerSlam pay-per-view. While Undertaker was headed to the back, he used the screen on the stage to help him walk. Right as he got to the back, he fell to his knees and then crawled for a second before getting back to his feet. It could just be a case of Taker selling, although it is odd that it happened right as he was almost backstage. I have reached out to WWE for more information, and we will post an update as soon as we get it.
