Marty Scurll recently signed a contract with ROH, so he will be staying with the promotion. AEW definitely wanted to sign him and even had plans for him.
According to a report by The Wrestling Observer Newsletter, AEW apparently planned on having Scurll as the leader of the Dark Order. He was supposed to be the Exalted One. Now AEW will find someone else owing to Scurll remaining with ROH.
Scurll had been the first choice to be the leader of the Dark Order and AEW for the 12/18 show in Corpus Christi with the heavily criticized beatdown, there was an idea for the show to end with the Scurll reveal, until ROH made Scurll such a great offer to stay
It is unknown who AEW will now choose to be the Exalted One. We will get to know in due time. Perhaps ROH and AEW will work out a partnership in the future.
