The Big Show will be out of action for the foreseeable future with a hip injury.
WWE put up a video on their Twitter account saying that Big Show suffered a right hip injury during the steel cage match against Braun Strowman on last Monday’s edition of Raw. Mike Rome cited a WWE.com article saying that Big Show realized something was wrong when he was thrown against the cage, breaking it and sending him to the floor. He also mentioned in the article that he felt something snap when coming off the top rope with an elbow, but worked through it via adrenaline.
While that is the kayfabe storyline, the real situation seems to be that this was something being planned for a while, at least before Raw went on the air. James McKenna from Pro Wrestling Sheet mentioned that Big Show was getting surgery for a “slight hip issue” right before the Raw broadcast started last week.
WWE’s video mentioned that Big Show was scheduled for surgery this week, but due to the events of Hurricane Irma it was instead pushed back to September 29th.
