Meltzer confirms that WWE creative has been informed Cena won't be on the show, and therefore won't be involved in the World Cup tournament, and that the team were charged with coming up with a suitable replacement. This will likely be addressed through a TV angle next week, although WWE is yet to confirm or deny anything themselves.
There is no further information on Bryan, though Meltzer notes that if the former SmackDown General Manager doesn't compete at Crown Jewel, WWE will hold his match with AJ Styles on a different show, hence why they're still running angles.
Raw or SmackDown should bring news of Cena's replacement, but Bryan's situation is far from resolved.
