Big Show reportedly missed the Greatest Royal Rumble due to an injury, according to Wrestling Observer's Dave Meltzer. 

Speaking on Wrestling Observer Radio, Meltzer said he doesn't know how severe Show's injury is, but it was enough to keep him from travelling to Saudi Arabia.

"Big Show was injured about three weeks ago. Again he was coming back from his injury and he got reinjured. So that’s why he wasn’t in the match. I don’t know how severe but it was severe enough."

"They wanted him in this match you could tell because look at all those big guys they brought in and except for [the Great Khali] you know [Big Show] is the biggest guy."

The Greatest Royal Rumble took place last Friday, and featured the historic 50-man Royal Rumble which was won by Braun Strowman.
