WWE announced that Elias is injured and will be forced to withdraw from the ongoing King of the Ring tournament.
He was scheduled to face Chad Gable tonight on Smackdown with the winner moving on to face Baron Corbin in the finals on Sunday at Clash of Champions.
It is believed that the injury is to his foot or ankle.
It's unclear if Gable will automatically advance based on Elias' injury or if he will have to wrestle someone else on today's show.
