Sometimes a concussion can be overlooked when it's part of a larger injury. This was never more evident than at SummerSlam '97 when Owen Hart gave "Stone Cold" Steve Austin a jumping sit-out inverted piledriver but failed to execute the move properly and spiked Austin right on his head. https://www.youtube.com/watch?v=OKYYsg-jMfU The move left Austin dazed and temporarily paralyed. Owen Hart, knowing something was wrong, did his best to buy some time and eventually an obviously injured Austin was able to slowly and awkwardly crawl towards Hart and roll him up in what could be one of the worst pinfalls ever (though understandably so). In the end, the blow to Austin's brain was the least of his worries as the botched piledriver had given Austin a broken neck which helped contribute to time out of the ring, a change in ring work style, and eventually, a shortened career.
