Gabriel Kidd has suffered a neck injury and will not be able to compete on Korakuen Hall cards on August 26 and 27, according the NJPW.
Both nights of shows have now had changes made to the cards.
A NJPW spokesman said: “We apologise to fans who were looking forward to seeing Kidd wrestle. We appreciate your understanding and wish Kidd the best in his recovery.”
Kidd tweeted: “In the grand scheme, a minor setback. Rest and recovery plan is in place. I’ll be back. ??”
