#1 Mick Foley

There have been plenty of instances of Superstars getting knocked out, but none have become more iconic than when Mick Foley met The Undertaker at King of the Ring 1998.
Competing as Mankind, Foley met the Deadman not inside Hell in a Cell, but instead on top of the structure.

Whilst the first fall off the side of the cage was planned, the second fall from up high certainly wasn’t.
Somehow able to continue the match after crashing through the announce table below, the Deadman and Foley would end up back on top of the structure, with The Undertaker chokeslamming the Hardcore legend.
Unfortunately, this caused the roof to break, and Foley fell through the roof to the mat below, and as a chair fell on Foley’s head after it bounced off the canvas, it’s no surprise that the three-time WWF Champion was knocked out cold.
Foley gave the performance of a lifetime, earning the future best-selling author, countless fans.
And speaking of Foley’s books, Mick would later write in his autobiography, that If he’d jumped any higher to take the chokeslam, he probably would’ve died from the unplanned fall and landing.
