Days shy of his 43rd birthday, Archer had been with New Japan Pro Wrestling the last three years working as both a singles and tag team wrestler, recently holding the company's U.S. title before losing it to Jon Moxley at the first night of January's Wrestle Kingdom.
News of his talks with AEW broke last month with the news becoming official Wednesday morning.
Archer's debut was the only thing announced for next week's Dynamite as the company has their Revolution pay-per-view this Saturday. It's assumed matches will be announced via their social media channels early next week.
Title matches on the show include AEW World Champion Chris Jericho defending against Moxley, Kenny Omega and Hangman Page looking to defend their AEW tag titles against the Young Bucks, and Nyla Rose defending her AEW women's title against Kris Statlander.
