The Undertaker and Goldberg faced off at the WWE Super Showdown event in Saudi Arabia. The Undertaker ended up winning after a sloppy match.
The match was scary to watch and many fans were concerned about the safety of both performers. Goldberg later admitted that he knocked himself out during the match and tried to finish.
There is some short footage floating around that shows Goldberg unable to stand after the match.
Here is the video (h/t to u/devw94 on Reddit):
