Fightful Select:
PWinsider has reported that Cody Rhodes has signed with WWE. While we haven't gained confirmation on a pen to paper, we can confirm that WWE has been operating as if Cody Rhodes is headed to the company.
Wrestling Observer, among others, has reported that the lined up match for Seth Rollins at WrestleMania is Cody Rhodes. Fightful has heard that has been the direction, but that other "huge" pitches were made along the way, but weren't sure if those even made it to Rhodes personally. However, Seth Rollins has been the direction for some time.
A source within WWE has indicated that travel has been set for Cody Rhodes for WrestleMania Sunday, but also specified that could change at any given moment to fit him wherever they want him to appear on the show. People close to Rhodes denied that travel had been set for the show, and said that was inaccurate info. However, those within WWE were working on the notion that Rhodes was planned for night 2 as of this week.
Those in All Elite Wrestling that we've spoken to believe Cody Rhodes won't appear until WrestleMania, though that's their personal speculation and not rooted in anything they've heard from the WWE side of things.
We have reached out to Rhodes and his team, but haven't heard back regarding inquiries of his signing.
As with anything, WWE plans are subject to change.
