During the most recent edition of Wrestling Observer Radio, Dave Meltzer confirmed the injury that sidelined Dalton Castle for the rest of 2024.
Despite being legitimately knocked out during a match on AEW Collision against Roderick Strong, Meltzer reported that Castle is out with a torn biceps, which will require surgery.
The match, which was stopped early after a flying knee from Strong caused the knockout, saw edits made to account for the changed finish.
