Despite being advertised to compete in the 50-man WWE Greatest Royal Rumble match in Saudi Arabia, Big Show did make the trip to Saudi Arabia with the WWE crew.
According to Dave Meltzer of Wrestling Observer Radio, Big Show suffered an injury about three weeks ago which is why he was unable to compete. Big Show has been recovering from surgery which took place in 2017, and he had been medically cleared to compete in the Greatest Royal Rumble, but he suffered some type of undisclosed injury and could not make the trip to Saudi Arabia.
No word at this time on how serious the injury is or how much more ring time Show might miss.
