According to the Wrestling Observer and reports from the event, Vader suffered a health scare after having a match in Japan earlier today, collapsing in the ring.

Vader was wrestling at Korakuen Hall during an event honoring the 45th Anniversary of Japanese wrestler Tatsumi Fujinami’s debut. The incident happened after a six-man tag match involving Vader ended and Vader collapsed in the ring. Vader managed to quickly regain consciousness and was able to walk to the back on his own.

Early speculation hinted at Vader suffering from dehydration or it possibly being related to his recent heart problems. Vader himself thinks the cause for the scare was instead him getting dropped on his head early in the match.
